Ask Equal Amounts

Why when you get comfortable around someone and you feel the relationship growing more problems develop?  There should be more respect and trust, no?  Or is that when people start taking advantage of others and start caring less?  Or maybe nothing is as good as it seems.  Even with open communication about everything problems still arise.  Maybe too much of a good thing is bad...Maybe it's just me...Maybe I ask too much.  But could you ever ask enough?  Maybe it will only work if you "ask equal amounts."
