Also, I noticed the other day that the cashier who was checking me out was snickering with the cashier at the next lane. When my cashier noticed me noticing her, she suppressed her laughter, which of course made me think they were laughing at me. I couldn't figure out why they would be, but I had that impression - and I don't get paranoid. I generally figure I'm not interesting enough to attract any attention - positive or negative.

Anyway my cashier had the grace to look embarrassed, and I still don't know if they were snickering about me or if they had some joke going on that wasn't appropriate. It doesn't matter, though. People who laugh at other people or who try to make other people uncomfortable are juvenile. Why spend any time worrying about whether you're living up to their standards or not?
