It depends upon the situation.
but mostly,
it boys.
Because most of the boys take their relationships for granted.
They don't take it seriously.
For us girls, we are so emotional and we can't hide the feeling of being hurt.
We are more emotional than boys. Most of us take life seriously and we don't take people for granted. Fro some reasons, we just love all the people around us who give us importance and tender loving care right?

That's only my opinion. haha~
