Next time you PASS a group of young ferals, try saying something like 'Morning, gents!', and flash a big smile. The PINHEAD who made the comment was probably irked by your passing. He probably gets passed a lot, and making derogatory remarks is his puerile way of feeling better.

I get passed all the time, and I'm old enough not to worry about it. But I have to say that when someone nods at me, or says "good morning" or "beautiful day, isn't it?" as they are passing, it feels good. Especially when it's a grandmother on a 3-speed doing the passing.
