That sucks man. I wonder how it got there. Maybe you were just that stoned.

You might wanna tell him your gonna quit, even if you aren't going to. Just make sure you aren't going to get caught again if you go that route.

Also know that it will be MUCH easier to get caught a second time. You come home and your eyes are red, regardless of whether you smoked or just had something in your eyes, hes gonna think your stoned.
