Speaking of hiding things from the youngins... Here's an amusing antecdote.
We "Acquired" our daughter already potty trained when she was 12. She's actually my wife's crazy cousin's daughter. (Yeah, we all got one somewhere!) Due to divorce, pot, drugs, alcohol, and a list of other things we 'removed' her from her parents custody. Judge Bum (Don't ask, that's his name.) said if we ever had a problem with her parents just call him on his cell.
Anyway, a couple of years ago we were at the lake house, and my son says, "Oh yeah, by the way, we're out of catnip!" I said, "Naaah, there's a giant bag in the laundry room in the upper cabinet."
My daughters eyes, who was 18 then, got so huge. I asked her what her problem was, and she said, "Oh my God! I thought that was pot, for years!!"
Seriously???
So yesterday when my wife and I went walkin' around the property, we found a bunch of catnip and ripped it out of the ground. We took it back and hung it upside down in the barn to dry out. I walked up to her room and leaned on her door jamb and waited until she noticed I was staring at her. She looked up from her computer and I said, "Hey..." She got a weird look as I inserted a dramatic pause, "We just hung up a bunch of pot plants in the barn to dry if you want to go smoke some."
Ya know, I never seem to have my camera when I really need it.
The look on her face was just priceless as she started screeching, "I thought that was pot!! I didn't know it was catnip!!"
