People used to think I did drugs (I don't, never did, and never will). Maybe they still do, who knows. I have a friend who kept wanting to get me drunk (I don't drink either) so that she could then get me high.
My last year of high school, I was like the only person at my lunch table who didn't smoke pot. I just don't see the point in doing drugs, and I don't trust anyone enough to do anything that would impair my judgement while in their presence. Well, I would trust my boyfriend enough, but he wouldn't want me to do something that stupid anyway.
When I was working at a store in the mall a couple years back, I remember some old woman making a comment about how I must be on drugs, just because I wouldn't give her a discount that I was instructed by the assistant manager to only give people if they asked about it before I completed the transaction (I wasn't allowed to go back and void it, and she waited until after I gave her the receipt to ask). Yes, doing my job means I must be on drugs.
