That's too bad, but if it's that painful to you, then I totally understand.

I hope you do have a better day. I guess I've just learned to live with other people's actions.
I was thinking about my races yesterday, and how I forgot about the guy who hit me 3 times from behind (spinning me out at least twice, maybe all 3 times), over the course of 2 consecutive races. At the start of the next race, I chatted telling him to stop hitting me. He responded with the canned "Good idea." It dawned on me that he was just making stupid mistakes, not being dirty. It just so happened that it was me 3 times in a row. I can't get mad at that, because last week I did the same thing to one guy twice in a race, and all I could think was he must think I'm doing it intentionally.
The 3rd race was funny, because I had the chance to pass him 2 or 3 times, but I didn't because I didn't want to be in front of him. I was happy to finish 4th instead of 12th. There was one point where he made a mistake and it was obvious I waited for him rather than pass him. My guess is that humiliated him way better than if I had just tried to take him out.
I guess my point is, (my) attitude is everything. Also, don't forget to check the replays. You never know what you'll find.
