How much is TOO much?

There are things you like and things you dont, and sometimes you just cant decide. People often tend to take advantage of vulnerability, not realising what the other person is going through. There is this thin line between being playful and being offensive, which if tampered, can lead to a lot of hidden grudges.
When a person close to you is given a lot of freedom, he/she can make you feel extremely transparent, in any relationship loosing the opacity can create a one sided gap. The gap further can widen and create a ridge, that is probably why one tries to rebuild layers after getting transparent. I have myself been a witness to a lot of such situations with a lot of people, and a lot of times you just can t decide what path to take. The question is when should one's defensive side finally enter the situation to take control. One should definately take the ball in their court to, I guess avoid a situation where the line may be crossed, well in time to change the direction.
A sudden realisation and learning just prompted up, giving me a lot of food for thought, it is interesting to study how people differ from each other, what are their emotional levels and how strongly a litttle alteration in any one emotion can lead to drastic introspections. I guess you guys should give it a thought too...
