Maybe she’s dancing with you?
“Rabbits have several ways to indicate playfulness, and there are lots of things most rabbits like to do as play. Rabbits like dancing in pairs and solo (more about the latter later). You may receive an invitation to pair dance, as evidenced by your rabbit running in circles around you. This means the rabbit is basically crazy about you, and terribly happy to see you, and is a very common enthusiastic greeting. A polite response is to wait patiently for a circle or three, and then do some dancing yourself, with a little spinning, walking back and forth in front of the rabbit, or circling around it. As described later, a few hops or head-flicks are also acceptable. Note that some rabbits don’t like being circled by a graceless hulk, and will get nervous, in which case you should probably just accept the dance as a gift. Dances should be concluded by offering a little grooming to your partner.”
