I don't hide them...my dad just thinks they're for incense...or at least that's what I think he thinks. I left one in my jeans the other day (with black shit all of the bottom) and he decided to do laundry and checked the pockets, but he just left it on the washer for me and didn't say anything. If anyone says anything about the one in my car I just say I gave someone from work a ride and she smoked a cig and forgot her lighter.
