Parental Dilemma

My Mum and Dad get irrationally upset whenever I lose a fight. Like they don't understand why I don't "just take their head off" or "get angry".

It's getting ridiculous. They were also unhappy that I won a fight but took damage and wondered why I didn't "just take them down". It's quite upsetting and off-putting. And I know if I do knock the next guy out I'm going to get the "I told you so" treatment like it was all their doing. It's getting really nippy.

EDIT: ironically now I'm angry.
