While Harley likes me well enough, he really likes Bruce. Which is fine, since Bruce is out of town so much. If they hadn't gotten along well from the start, it'd be much harder for them to establish a good relationship. But it does make for funny little rituals.

Harley has a habit of grabbing your fingers pretty tightly with his toes while he's sitting on your hand, and leaning in the direction he wants to go. Once or twice he has even fallen off, from leaning so hard. Apparently African Greys are known for this behavior. Since Harley is so Massive and Willful, we usually take him where he wants to go. Quickly.
When Bruce goes out of town, Harley and I often have to walk around the apartment so Harley can see that Bruce isn't hiding somewhere. Last night we had to walk around the apartment three times. Aw.
