years ago, I took my sons to a card show where Moose and Billy Ripken where signing.
My youngest, probably about 7 or 8 who was very shy, managed to tell them they were his 2 favorite players, Moose was first, he signed without even looking up. Billy seemed to realize that my son was disappointed and got up and high fives him. and thanked him. At that point, Moose extended his hand.and smiled. i did not think moose was rude, but different for sure
