I would just keep being freindly with her - pat her but don't pick her up. Most rabbits don't like being picked up anyway. I would just make sure that when you are with Sophie (whom I bet is as cute as can be! ) you make sure you are always calm, and move slowly. Pet her just on the nose and head (bunnies favorite spot) and just sit quietly with her. Is she allowed to run around, or does she stay in a cage all the time? If she's usually in the cage, DON'T reach in to take her out - this can make a bunny feel very threatened, and like her home isn't safe. Just open the door and let her come out on her own, or at least wait until she comes to the entrance.

And NEVER try to touch her tail! Our bunny would definitely bite anyone who did that!

Be patient, quiet and calm, and I'm sure she will learn you are her friend.
