I got caught last May and felt exactly like you. Back then I was a newb smoker and I didn't know anything about weed besides the facts that it was green and got me high. I stopped for about two weeks but then summer began and there is no point in not smoking during the summer. IMO it is the best time in the world to smoke, especially on a bright warm sunny day. sorry, im getting off topic.

by the way, mention to your parents how long and how frequent you've been smoking and then follow it up with "the fact that you didn't even notice just about says it all"
