I hate being dropped when I think I'm out for a fun ride. If its a race it angers me for competative reasons. I really think if you go out for a ride with somebody else you should stick with them no matter how slow they are. Of course this is coming from somebody who rides with men a lot, ususally men get so competative they'll drop their own wives, mothers, and daughters if somebody wants to go faster then them. Even if I do drop somebody I'm with it is to chase a faster person until I catch them then come back and ride with my friend. However, if you agree that it is ok for one person to go ahead, fine. I usually don't though because I know how bad it feels to be dropped by a friend.
