A gymnast I know recently moved from one gym to another. The girl is a talent and moved to a gym with superior coaching. Each time this gymnast sees her old HC, she runs up to her and enthusiastically tries to give her old coach a hug. She is met with a viscious coldness and eye-rolling. My first instinct is to think about what a mean person the old HC is. Then I thought, maybe there are legitimate reasons why the coach is being so standoffish. Are there legitimate reasons to not show any affection to one of your ex-gymnasts who has moved on or is this purely unacceptable?
