Probably telling my brother I tried to "aquire" our dog.
Dude, I would always try to "acquire" animals as well!
Okay, not seriously, but it would cross my mind whenever I was touching/petting animals (like a neighbors' dog, my pet bird, a screech owl at the fair as this thing where you paid money and would then get your pick holding the animal--I was so excited and saved up my money so I could get my picture with a
red-tailed hawk (which I of course totally geeked out about whenever I saw it--Tobias!) the following year, but noooo they stopped allowing it then!), and I would pretend to do so....:p I always loved to imagine turning into animals!
I can't think of any embarassing encounters exactly except reading the books themselves sometimes I guess, since not everyone is enlightened and realizes they're awesome books....
