In a huge giant theater where maybe five people are sitting all spaced out through the entire room, sit right in front of me even though I already have my feet up on the chair.
Is it reasonable for me to be annoyed? Probably not, as I only paid for one ticket which entitles me to the seat I'm already in. But I'm still irritated.
And then I'm really irritated when you and your group are talking and text messaging each other. Seriously, why did you have sit in front of me and my boyfriend?
