Having only recently dipped my figurative toes in the world that is being responsible for school age children, I can tell you that unless you are some kind of masochist, you want to steer clear of most school events. It's probably also worth mentioning that you'll inevitably be roped into going to said events, alone, and will definitely send texts that every mom sends her partner during her kid's school events, because how in the ever loving hell are you expected to make it through these things solo, without the help of your cellular device? That's right. You can't.
Class trips. PTA meetings. Sports events. School concerts. Bake sales. Fundraising events. Each one of these belongs in its own circle of hell that, I'm convinced, even Dante would have a difficult time surviving. I seriously don't know how some moms manage to do it all, and if that makes me a "crap mom," I guess I can live with that. I mean, I'm an introvert to begin with, so being forced to interact with outgoing mothers who actually enjoy these events is pretty far down my priority list.
Still, you can't hide from the inevitable after-school event, forever. I'm not saying you'll need to participate in every school function ever offered to your child, but you will find yourself at a few. When that happens, there's only one thing for you to do: send your partner texts so that you can appear busy and therefore avoid as much adult interaction as humanly possible, while simultaneously forcing your partner to experience the misery with you because, hey, that's what partners are for.
