He's a People Person, really.

Our bathroom is converted from a large pantry; being frugal midwesterners, who ever put in the bathroom did not change the pantry door. We have a swinging door that does not reach to the floor. This benefits Zeus during his moments of separation anxiety. If only one person is home and -horrors!- decides to use the bathroom, Zeus comes trotting along to plop himself down outside the bathroom with his snout underneath the door.

The rest of us find this slightly annoying; Equuschick, however, thinks it's adorable and is always willing to coddle her doggie. :-)
