“Then why e-mail her mother saying the daughter sucks?” My guess, only getting one side of the story, maybe the coach is sick of getting grief from your sister, you did say that she had a big mouth.
Then tell my sister she sucks, not her daughter!
And the two things my sister spoke out about had to do with legitimate concerns held by a group of parents. Everything seemed fine for a while after that. She didn’t take it past talking to the coach. Sorry if I gave the impression she was complaining to the school, she hasn’t. And her big mouth comes in handy when organizing and fund raising for camps and travel. Other years, or so she thought, she and the coach had a good
relationship.
People that say parents shouldn’t be involved— coaches almost demand it, fund raising, transportation to distance camps and tournaments, hotel rooms, all are done by parent volunteers. When I was young we played local, now there’s interstate travel, Club, private lessons, all to remain competitive. All done per coaches request by parents like my sister, while
he collects the paycheck. And the kids just want to play and win. And my sister has never made an issue about anything directly related only to my niece.
