Swear at your parent

nopes, didn't swear on anything.

I've never swear at my parents. That's such a disgraceful action!!

Swearing on anybody is not good habit. Actually it becomes a habit once you do it a few times. I remember myself swearing on parents in my very early childhood but i have stopped it now. I find it very disgusting when somebody swears on his/her parents. People should stop swearing and instead start being truthfull.
