He has an older brother (5 years older) who is a very good athlete, however my 10 year old is also a very good athlete. The
competition comes with all games...not just athletics. It could be darts, monopoly, kickball at school, team sports, anything in gym class, etc. If he doesn't win, he gets very angry. He absolutely hates to lose. He will stomp away, sometimes scream, pout, etc. We have had multiple conversations about being a good sport and winning and losing and he understands it all.
