Daddy, why do you do drugs?

That was a question asked by my three year old at the dinner table about a month ago, oh yeah, and he practically had tears in his eyes.  Talk about a jaw dropper.  Ok, so I smoked pot once, but that was 7 years ago and it was one time.  And how the hell does my three year old know about this?  Well, he doesn't, duh. 
My son, got this from his big brother, who got this from our wonderful education system.  Apparently the teachers are telling the students, that alcohol and beer are drugs.  Well, dad drinks beer occasionaly, so dad does drugs.  What a great thing for my kids to think, especially with the employment field I'm trying to enter.  I can just see when the background check is done, and the investigator wants to talk to my family.  "Yeah, my dad does drugs."  I understand and am greatful that they teach about drugs, but for GOD sakes, when you're telling the freakin' 5&6 year olds about drugs and alcohol, you need to freakin' explain to them that beer is ok to drink if you are an adult and it is not done in excess, blah blah blah.
I was so pissed off I almost called the school.  What do you think that made my kids think of me when they're teacher said that alcohol is a drug, without explaining it to them?  "Holy cow, my dad's a druggie."  "My dad is one of those guys that hangs around on the other side of the fence and tries to get little kids to smoke and drink "Jesus Juice".  Oh yeah, and if you smoke, you'll stink and have terrible stinky breathe, and your hair will stink.  Oh yeah, and guess what smoking is a drug.  Guess what else I enjoy doing, I enjoy smoking a cigar every now and then with, guess what, a beer.  So that's double bad isn't it.  I'm really surprised that the school hasn't sent children's services out to see me. 
So, if I ever disapear from the website without mentioning it first, it's cause AlaskaDad is a druggie.
