I'd like to read it! 😀
There are quotes from different episodes:
Season 1, Nightmares:
Buffy: I just can't believe a kiddie league coach would do something like that. [beating a child]
Xander: Well, you obviously haven't played kiddie league. I'm surprised it wasn't one of the parents.
(This can be taken as Xander admitting his father hit him because he lost a match.)
Season 1, Out of Mind, Out of Sight:
Xander: Oh, hey, do you wanna come to our place tonight for dinner? Mom's making her famous phone call to the
Chinese place.
Willow: Xander, do you guys even have a stove?
(Shows that Xander's mom can't cook)
Season 2, Inca Mummy Girl:
Xander: My dad tried to sell me to some Armenians once. Does that count?
(This is too disturbing)
Season 2, Surprise:
Xander: (on the phone) Mom, hi. [Who's this?] Xander.
(Xander's mom doesn't recognize her only son's voice on the phone. Too drunk perhaps?)
Season 2, Bewitched, Bothered and Bewildered:
Harmony: God! (looks Xander up and down) Y'know, I'm glad your mom stopped working at the drive-through long enough to dress you.
(His mom's job. I'm guessing his father was able to get a job at this point and his mother doesn't have to support the family anymore.)
Season 3, Amends:
Xander: (with false heartiness) Well, I'll be enjoying my annual Christmas Eve camp-out. See, I take my sleeping bag outside and I go to sleep on the grass.
Willow: Sounds fun.
Xander: Yeah, I like to look at the stars, you know? Feel the whole nature vibe.
Cordelia: (smiling smugly) I thought you slept outside to avoid your family's drunken Christmas fights.
Xander gives her a look like he expected no less from her.
Xander: Yes. And that was a confidence I was hoping you would share with everyone.
(This one is interesting. It seems Xander told Cordelia about his problems with his family, and he didn't tell Willow, his best friend. Does that say something about Xander's feelings for Cordelia? Did he trust her more than Willow at some point during their relationship?)
Season 4, the Freshman:
Xander: Basically, I got as far as Oxnard and the engine fell out of my car, and that was literally. So, I ended up washing dishes at 'The Fabulous Ladies Night Club' for about a month and a half while I tried to pay for the repairs. No one really bothered me or even spoke to me until one night when one of the male strippers called in sick and no power on this earth will make me tell you the rest of that story. Suffice to say I traded my car in for one that wasn't entirely made of rust, came trundling back home to the arms of my loving parents, where everything was exactly as it was except I sleep in the basement and I have to pay rent. How's college?
Season 4, Living Conditions:
Buffy: What's the deal Xand, parents not feeding you?
Xander: Sure they do, for a price.
(Xander is also expected to pay for the food he eats from his parents' refrigerator.)
Season 4, Restless:
XANDER: (whispers) That's not the way out.
(The door bursts open. Xander looks down at himself, then back up the stairs.)
VOICE: What the hell is wrong with you?
(Xander looks chastised.)
(We see a man silhouetted in the doorway above. It's Xander's dad.)
DAD: You won't come upstairs? What are you ... ashamed of us? Your mother's crying her guts out!
XANDER: You don't understand.
DAD: No. You don't understand. (Starts down the stairs, stomping angrily) The line ends here with us, and you're not gonna change that.
(Xander looking down, unable to look at his dad.)
DAD: You haven't got the heart.
(Suddenly Dad shoves his hand into Xander's chest.)
Season Five, the Replacement:
Upstairs we hear a door slam.
XANDER: (looking up) Ah, I guess the folks are back.
We can hear voices yelling at each other. Xander, Anya, and Riley look uncomfortable. Buffy is oblivious.
XANDER: No, no, I was wrong. Just incompetent burglars.
More yelling from upstairs. Then there's a bang (another door slamming?). Plaster dust from the ceiling drifts down onto Anya.
XANDER: Yeah, maybe it's definitely time to start looking for a new place. Something a little nicer. Buffy, you've been to Hell. They have one-bedrooms, right?
Season 5, Forever:
XANDER: You going home?
WILLOW: I'm gonna stop by my mom's first. Been doing that a lot lately.
XANDER: Yeah. I actually might stop by your mom's too. (she looks at him) Well, I'm not going to *my* place. Those people are scary.
These are some quotes from seasons 1 to 5. Most of S6 is about Xander being scared of becoming his father. S7 has only one quote in Him where Xander says that fighting reminds him of Christmas at his parents' house.
Hope I helped. I'm sure I missed a few quotes here and there, though.
