*LOL* I talk to my kid all the time, AND he talks to me. However, there are certain things that are off-limits to me as a mother: I am not allowed to go on the football field or the wrestling mat if he is injured (unless he is unconcious), nor can I discuss certain guy things like underwear. These are treated with the same horror that I got from my daughter when she thought I may have read her diary. And yes, everytime that drug commercial comes on I ask my kid about drugs. ;-)
I do get what you are saying tho - as a teacher I am always amazed at the vast number of kids who don't have anyone looking out for them. It's really sad.
