2 years ago, we had a girl and her mom come to our gym from what her mom called a "TOPs" program... We are a YMCA program. We compete USAG routines judged by USAG Judges... same as her "TOPs" team. Whenever someone new comes to our gym, I greet them with a warm smile. Being a Y program, we have rec classes and team practice in the same gym... however, unlike some YMCAs, we actually have a gym devoted JUST to gymnastics - so no set up and tear down for each practice.
Well, her daughter had been a Level 4 the previous season (the season we had just completed)... so we were in fun, uptraining, not super-serious mode. We had things like "kip club" for anyone who didn't have a kip and "Fly Away club" for girls who had competed Level 5, etc. Her daughter goes to school with my gymmie (the only 2 from their school in the program and we drive a half hour to get there, and she had been driving 45 minutes to an hour to get to her old gym).
The mom was badmouthing our coaches - lack of discipline, girls standing around chatting, not correcting bent arms on a very first ever kip attempt, there shouldn't be knots in the climbing rope, all kinds of stuff. And CONSTANTLY comparing our practice (which she was watching from bleachers IN the gym) to theirs (which she watched from behind glass). She came for about a month... every time knocking one thing or another. I observed her daughter. She may have gone to a gym with a TOPs program, but there was no way she was in it! She didn't have the flexibility or the skills for it. After that month, she left... I saw her daughter again last month at a school variety show. She has switched to dance - mostly tap from what I saw. Her mom was sitting 2 rows behind me. I could hear her putting down other acts after they performed (One girl did gymnastics - self-taught, no lessons ever... about Level 4-5 skills. The mother was saying she should point her toes, her daughter was better and could do that stuff 4 years ago, and on and on). It took all my strength not to turn around and tell her off.
Some mothers just like the sound of their own voices. I hope your visiting mom never returns!
