All I have to say is,
WHY would you do that?! They put up with you, and are there for you no matter what (well, at least that's been my experience).
If you think about all of your stuff they've put up with for your lifetime, and all the sacrifices and things they've given up-- just for you-- I think it's pretty darn selfish and ungrateful to disrespect them.
Of course, I've had great parents. I'm incredibly thankful for them, and for the examples they have been to me. I know that parents are not perfect, but I have to say that as far as parenting "perfection" goes, mine are definitely at the top of the list. I can only imagine how disappointed and hurt they would be with me if I did that. Ouch.
