My wife had placed her belt in the closet and did not notice that the end of the belt was left dangling out of the closet.
I teased my little one that there's a cat in the cupboard, so I opened and closed the closet door quickly and mimicing the nasty hisses. My youngest daughter was really surprised that there "was" a cat in the closet and went around telling her brother & sister.
She was brave enough to actually open the closet door on her own, and found that it was just a belt.
Well, surprises ain't over yet. For the next few nights, two of my younger kids were going around at home with the end of a belt out of their pyjama pants, "meowing" and grabbing one another's "tail" .... Geeeezzzzz ... what have I started!!??
