My Mom has told me to "get a life" before and that I'm not only wasting my own life, but wasting her and my father's as well. The latter was just last week.
Also I've had my Dad say some pretty nasty things in heated arguments which I'd like to think he doesn't mean, but I suspect, deep down, he really does a lot of the time. Once he told me I was nothing/not shit, another time he said that I thought I was a girl. He once yelled at me to go sit at the park and read or do whatever it is that "weird guys like you do". And another time soon after some suicidal ideation's of mine that he found out about he told me I could go take a whole bottle of pills for all he cared. These were all said in the heat of the moment, mind you. But it didn't make them any better to hear.
Then again, my Dad has the bad habit of saying extremely cruel and spiteful things when he's angry. Just last month he was in a foul mood and during an argument with my Mom said that he was embarrassed of her because of her weight and laziness. The reason for all of his anger was absolutely ridiculous, but I won't go into that.
