So your opinion people. Was Joyce right, was she just being a good mother or was Joyce wrong and should have stayed out of her daughter's business? What's your view on the Joyce/Angel talk?
Personally, I never really saw Buffy as being particularly mature at that point, and as for Joyce having the "right" to speak to Angel, of course she dis, and would have had that exact same right whether Buffy was eighteen twenty eight, or fifty eight. That right comes with being a caring parent, and it has absolutely nothing whatsoever to do with age. And, as far as going behind Buffy's back is concerned, That was the only way that she could do what she honestly believed that she should do. Obviously, she would have had no luck whatsoever in trying to convince Buffy that any sort of relationship with Angel was doomed before it started (And she was absolutely right. Any time that Buffy and Angel "get together," something bad happens, quite often resulting in someone dying) so she went to Angel on the hope that he could see what Buffy refused to.
And, when you get right down to it, the entire series is about people interfering with Buffy's life, from the Shadow Men, who created the First Slayer and made her calling a perpetual thing, to the Watcher's Council, who tracked her down and drafted, not recruited, her into the duties and responsibilities of the Slayer. Joyce did it, the Watchers did it, Giles did it, Angel did it, Xander did it, Willow did it, the monks who made Buffy the guardian of the Key did it, even Andrew managed to, throughout the entire 7 seasons on TV, on into Season 8, and undoubtedly will continue into Season 9, and every season thereafter. You might say, if everyone had just let Buffy live out her life unmolested, she would have been able to, as Kristy Swanson said in the original movie, "graduated from high school, gone to Europe, married Christian Slater, , and die." It's that interference that makes Buffy possible. Without it, she would have been just another airhead cheerleader.
