Personal Space Again

OK, maybe it's just me...but remember I had that gym incident with the locker thing fairly recently...well now two days this week I've kind of run into something again, this time with the bikes. At the main location I work out at, there are 10 regular bikes, all in a row, and granted, they aren't on top of each other like they are at another location I hit sometimes, but still, they are close enough...anyway, got there this morning at 5:45 and decided to bike then run...all 10 were free, I took one on the end...10 minutes into my ride and a guy comes along, still all of them free, and he takes the bike NEXT to me...he had headphones on, so no, it wasn't so he could be close and try to hit on me (plus I was reading a book), he was older, so that could be part of it, just lack of the understanding of the unwritten rule to leave a space if you can (a couple minutes later another guy came along and took the bike 2 over from this guy, leaving an opening)?? Anyway, not THAT big of a deal except for the fact that within about another 5 minutes he started to sweat, and smell...ughh...yet another reason I don't like running on the treadmill at the gym, when it's busy...I always get sweaty guy next to me that starts to really stink soon after...now I'm not saying I smell great when I'm working out, cause I know I don't, but if at all possible, I leave space between myself and the next person over!! Sigh...
