So you know a while back I was complaining about how often my gf's parents stayed over?
Well, just to give you an idea what I mean... Since last Friday, it's been as such: Saturday Night, her mum stayed over, Sunday night, her mum stayed over, Monday night, her dad stayed over, Tuesday night, her mum stayed over, Wednesday night her dad stayed over, tonight her dad is here and it wouldn't be unreasonable to assume that he's staying over. And by staying over I do mean staying over night. And they're hardly visiting for a holiday because that would suggest that it'd been a while since they had visited and/or you don't see them regularly, rather than it just being the norm.
Seriously, when you move out/move in with someone, I hardly think it's unreasonable to want to carve an independent life for yourselves, not just de facto live under their parent's roof, unless you actually move in to their parent's house.
I know, I'm probably a terrible person.
