Parents weren't allowed IN the room where my kiddos took Ballet Lessons but the studio had a 1way mirror, so they could sit in the lounge room and watch, so I was fine with that.
Dropping my kiddo off at her lesson would be the most pointless thing I could do. The barn is 45mins from our house and 20mins from ANYTHING. Her lesson is 30 - 45mins long and as she's all of 6, she can't tack or un-tack the horse, so I couldn't make it home and back in her lesson time. Now I could go into *town* but I'd make it there in time to turn back and we're talking a town that doesn't even have a grocery store. There's a couple gas stations, couple restaurants, a convenience store, an auction house and a hardware store. So there would be zero point in going to town.
My kids watch my lessons during the summer (I can't leave them home alone), so it's all fair! LOL
