So typically my response to the whole LJBF thing is to say:
Honestly I have enough female friends as it is right now. I really don't have the time or the desire to add another one to the list.
Maybe it sounds a little bitter but it's true, unless I really like a girl as a person and could see myself wanting to hang out with her as a bud, I don't see the point.
Is it too harsh? It's nearly impossible to escape the Friend Zone anyway... so is there a point in agreeing to just be friends?
