She's not a teacher, she's a PE teacher -- you know the saying:Those who can, do.
Those who can't, teach.
Those who can't teach, teach PE.*
Plus, I think she teaches at the YMCA, not an actual school -- so at least she hasn't passed any kind of state certification. Nonetheless, I wouldn't let her anywhere near my kid -- at the Y or otherwise.
*I keed! I keed! I mean no disrespect to teachers -- My mom & sister are both teachers & I know what an important and under-recognized job it is!!
