In a way, I just feel sorry for him. Two buddies and I rode about 100 mi (161 km) yesterday, and it seemed that everyone was riding in groups. All of them waived with what my old German language professor would have called, "mit gefuehl!" (with feeling!)
My philosophy comes in part from years of severe depression. I had lived on the edge of suicide since I was about 9 or 10. At 44, I'm finally in good shape now, thanks to God, a wonderful family, truly great friends, and an inspired doctor in addition to medicines unavailable a decade or two ago. Anyhoo, after coming out of that, I just feel that if I have something good to say to- or something friendly to do for- someone, I say it or do it. Why hold it in? The opportunities slip by and are gone. Giving someone a smile or laugh is something precious that lasts, as is also the case for lending a hand.
Obviously, I think about things a lot, but I can say that most of the folks here feel the same way, whether they think about it in the same terms. [edit]By the way, I'm not talking about how folks here feel about the wave.[/edit]
