I wave anyway. If they don't wave back, that's their decision and only they lose from it. If they'd rather be an ass, they're the ones living as an ass, not me.
If there were more riders I'd probably get tired of it, but it's only 2 or 3 at most on a ride. I'm thrilled; prior to this year I didn't see 2 or 3 in a month, but there's a lot more now.
