My Commute I

On my commute to work downtown this morning, I espied a rather curious person. As the bus turned west off of Lake Shore, there, on the sidelines of the Northwestern tennis courts, just 20 meters off port side, was a woman with the most gigantic breasts I have ever seen. You might be thinking, "men, so typical." Normally, I would agree with you. But trust me when I say this was no triviality. EVERYONE on the bus turned to look--men, women, and, if I can trust my peripheral vision, the bus driver. I thought this woman was packing water balloons or wearing her backpack backward or something, but no, boobs. She looked about 50, but lefty and righty definitely were younger. And the worst part about it was that she was about to play tennis. I'm sure that would have been quite a match.

Question: why is it that two bus drivers honk and/or wave to each other on the road, but only if both work for the same company? I noticed it in Europe, and it happens here too. In Chicago, Pace/Pace = friendly, CTA/CTA = friendly, but Pace vs. CTA = unfriendly. Is the rivalry that fierce? At least there's some amity on buses, though, because it never occurs among taxis, whether the drivers work for the same company or not. They just drive around like zombies and don't seem to pay attention to anything except getting to the passenger's destination and beginning their next waiting session.
