I live alone with my dog most of the year, and love that. I get quite testy when I have to give up my quiet evenings at home, though I occasionally do. I often feel like there is so much that constantly demand your attention - from work, to family and friends, to random strangers ( I frequently strike up acquaintances whole commuting e.g.) - that my solitude at home is necessary for my well being.
For about 5 months out of the year I move out to the family summer house, and then I live mainly with my dad, aunt, and a couple who rent an apartment in the house. Sometimes cousins, nephews etc are also there.
I have my own apartment in that house, so I don’t have to share kitchen with anybody, but it is still quite taxing to be there. I love/hate it, because you have to see and talk to people every day. And they will just saunter in if they haven’t seen you in an hour or two. And you’re expected to see each other for various meals and coffees throughout the day. It is nice, but it also drives me mental. (It is on an island, so you can’t readily escape). But when it is time to go home I always miss it, and when the elder generation passes on I will miss it loads!
