I used to have a blue&gold (BB). One morning I was eating cereal, she climbed up my chair, and bit my shoulder and cheek....for no reason at all. It wasn't too hard, but it did leave a mark. Most of the time she was very sweet though.
Hahaha, and like Cendalla said, BB also enjoyed trying to break my ear drums (when she wasn't randomly talking)
I miss her.
