Some rabbits will lick objects around you, rather than your body or the clothes you're wearing. This is used to indicate that they like you very much even though you're a subordinate. It will be performed very clearly in your view and while watching you. They seem particularly to choose objects that have your scent, such as places where you sit or clothing you're removed. I think it's fair to interpret this as giving you the gift of being groomed, though indirectly.
