my beardie dances at the glass when he's hungry (it's always on the side of the tank where i keep his worm tub). but when he wants out he dances on the other side of the tank, guess that way he's being extra clear about his desires.
his new favorite thing is dancing to be let out right as i'm getting ready to leave for work, which makes it that much more difficult to leave because i always want to hold him when he does that (he's so evil).
