The moms of competitive skaters see each other at the same time every day to share a similar routine. They have a certain unspoken posture about them -- not only do they support a competitive skater with the intentional characteristics of overlapping muses but they also share quite similar home lives. Severely isolated from standard workaday corporate ladies they build their own castle in the sky of who said what or how the club is fairing or how they feel about traveling to the next competition. Essentially they all share similar jobs.
Most of the rink smalltalk about coaches or equipment transpires between the moms when their kids are little and approaching harness jumping. Skates and blades and coaches and costume (and all of that) get fully talked through and settled into quiet understanding before their kids are 10. When you go to a freestyle of juniors the moms are verbally silent, having already discussed the mundane nuances of the sport amongst themselves many years ago. Naturally at this point they are quite a bit noisier mentally, and given the time they have previously invested they harbor more severe expectations.
Some of this gets flittered out when the gals clear the ice for the periodic zamboni. It's just natural that moms will chat with their kids about how they're feeling with their skating and give rather pointed remarks as to technique, or encouragement when elements are behaving strangely. You don't hear a lot of talk about "What did your coach say" as moms purposefully aim their freestyle parental time in a different direction than what the coach says.
Some of this is normal childrearing behavior of a mom raising an erudite teen girl (mom is applying various degrees of pressure to her teen daughter). The skater understands how her body reacts to the ice and the sociology of her fellow skaters. She feels supported by her coach and can do no harm within the context of trying her best given the vagaries of ice, feelings, body variance, and how her boots fit today. The mom though often has loftier objectives since she is aware of the cost. Additionally mom and daughter span a wide gap of life perspective (after all the mother has already been through childbirth).
A subtext of this happens whether your child skates or not: a parent is imminently interested in the future success of her child. Many moms are contemplating where their kid will end up in ten years. A skater is looking ahead to the next year at most. In other words their vision of the kid's timeline is very different.
To facilitate communication a parent parses their longer range expectations into terms of shorter one-year objectives that the child can digest. Conflict nestles within the demands of higher perfection inherent within the longer timeline. With only a vision extended to a single year, a skater thinks Hey if I'm a little bit off on this move it won't be a big deal because there's a good chance that I'll straighten it out by the end of the year when I'm ready to advance. The parent though sees compounding shortfalls of immaturity; compared to their mind's eye view of where their skater should be in ten years, each deficit in skill or grace appears as a worsening obstacle that gets piled onto the perfection they would eventually like their kid to achieve. Few parents set out to spend thousands of dollars just to have their kid have fun on the ice for a decade.
