Yeah, they're not bad to look at...but they hurt and you can't run with them. I hate it when you know the other person isn't listening because of them or when everyone knows your shirt is unbuttoned or has pulled downwards and nobody says anything...meh.
I don't want to sound odd but I have to get this off my chest (haha. no pun intended, really) yesterday at work this young girl tried on a costume made for girls/women with boobs, she didn't have boobs. This was an issue, but not my problem until I commented that I liked the costume. At this moment the girl's mother informed me that if her daughter couldn't fill out the top I definitly couldn't. and I am sorry flat chested girl's mother, but I am a 'C' cup. thank you very much. I am quite average+ for my body type and that is all.
but yes, boobs are kind of annoying during running.
