Musical waiting is shorter than swimming waiting, I get just under two hours sitting about at Saturday morning music centre. It's warm and there's chairs and tea and I'm always very grateful that I'm not standing on a touchline in the rain. I usually take my knitting as it provides a good excuse to not talk to anyone.
Mine are bigger but there is still quite a bit of waiting about. I sit in a coffee shop and knit. It's the best " me time" I get!
My parents I see in retrospect were saints for this, driving 45mins each way 3x week for music school. They bought a camper van, I'm sure mostly because of this, so dad could have a brew and read his book in a comfy chair
