Have you ever met someone who doesn't care? Their response is always in way that lets you know that they could care less how you feel about it.
Its always OK for them to do and say what they want but as soon as the shoe is on the other fit they are all up in arms about your response. The frustration that they have is supposed to be acknowledged more than yours... (well, in their eyes). This pisses me off to the highest level especially after being married for more than a decade.
I always have to be considerate and think of everyone while people are so brash with their statements. It shouldn't take for someone to make it clear they have been hurt for their significant other to start thinking before speaking. If I can think before I speak then why can't you and if your intent is to just hurt me then why are you here?
