It is amazing. I wonder if it was a rehabilitated/released seal?
All I can say is that this is not a normal experience with a wild animal and would like to mention that seals do have sharp teeth and will bite. I don't want people trying to snuggle with wild seals.

Also, she seemed to speak seal and was able to interpret the seal's body language. I liked that she didn't move towards it and let it come to her and she never used her hands to pet the seal.
