girls: the way they think

usually, guys are chivalrous towards their female friends (i mean friends from the opposite sex, and not girlfriends) and help them out proactively in situations where they wouldn't bother if the friend in need was a guy (unless asked by the guy, of course).
my question is - do girls think of this as friends helping friends, or as making use of guys?
just overheard a conversation which made me wonder about this. If the latter is true , even for, say, 25% of the cases, then that's ******

any lateral views?

PS: given the no. of comments on my blog lately, any views at all??
