Say a sibling, just because you are not able to do one thing, tells you that you cannot do anything. Then when you get upset about it, they tell you to "take a joke"
Ah yes I'll fucking take this "joke"
I'll take it and throw it out the fucking window because your sense of humor is rather annoying
I could give more example but I'd be here a while
But family members may brush this off, but it can be to the point where it's not joking around. In other words, bullying.
