what do you consider to be leading someone on?

the urban dictionary says that: It usually means that a girl or guy is behaving in a teasing or sexy way that dupes someone into thinking that they will be willing to have a relationship with them but at the last minute they back out of the deal.

so what do you do when someone you know leads some one you care about on? is it your place to say "hey buddy, you might really like her a lot, but she's saying that you two are just friends. plus she dicking around with some one else"?
or is it not your place to say anything, to hope that they figure it out before they get their heart either ripped out of their chest or completely trampled on.
then after, do you have a right to not really like the person who did the ripping out? are you obligated to protect one friend while sacrificing another?

i think i am a little biased on this issue. on one hand, i'd like to be pissed off at the person doing this. but also, is it any of my business at all? when i brought this up to my best friend, i was told that no, it wasn't my place to interfere, that if someone wanted to be a bitch and lead someone else on, that was their business and none of mine. but honestly, do i have to sit around and watch someone get hurt? i'm not sure.


"are you mad at me for something?"
"do i have any reason to be mad at you?"
"no"
"then you should assume that i'm not mad"


people make life difficult. and everyone wonders why i enjoy beling by myself just as much as i like being with other people. less complication if you hang out by yourself, less drama, and then you can tell people honestly "no, i have no clue what you are talking about. i'm not involved in that bit o' drama"

sheesh
