Even though I'm a grown adult, there are still certain things I don't feel comfortable doing in front of my parents — kissing, drinking too much, etc. — some things are just meant for your peers. Since I'm not a smoker, I can only assume that I'd feel the same way about smoking cigarettes, but it's pretty clear from these pics that Katherine Heigl doesn't agree! Of course, all family dynamics are different so tell me, are there still things that you don't do in front of your parents? And if so, what are they?
