If I get on a bus alone and there is a spare two-seat, I'll sit in it (window side) - as will pretty much everyone else who gets on a bus alone in my experience.
If I get on a bus with DD, and it is half full of people all sitting alone in two-seats, she gets annoyed because we can't sit together.
I've explained to her that if you got on a less than half full bus and you sat next to someone when there were empty two-seats available, they would think you were some kind of weirdo/space invader. But I also think she has a point.
So is either of us BU?
Sorry it's a bit of a tame AIBU (and it's my first) but I'm interested in what people think.
