It's nice when a friend calls at the last minute to offer you a spare ticket they happen to have to a concert. I like to tag along for an impromptu get-together, but sometimes I'm too deep into my night to drop everything and go to a show. I usually feel a little guilty for not having a more adventurous spirit and going along, so I'll suggest someone who might be interested in joining them for the show. If you and I are ever in this situation, don't say, "Oh, he can't go." And then if I suggest another person, definitely don't say, "Yeah, she's busy, too." I'd prefer to just keep on thinking that I was your first choice when you got your hands on that extra ticket.
