So. Before I had taken my pointe test one of my classmates (who had recently started pointe) was asking me about my plans in that direction. She was very encouraging but also assured me that I would probably wonder what I had been thinking as soon as I actually got up there. And I said "oh yeah. Like when you're 11 and you can't wait for your period to start, right?" and she said "EXACTLY"
You see, if you are a dude you totally don't get this. If you are of a certain age (say, 55+) and your mother was tight-lipped about that sort of thing you don't get it, either. But for women of my generation there were secret girls-only classes once a year in 5th and 6th grade. And there was "Are You There God? It's Me, Margaret" and as soon as we hit ten we were standing around like "OH MY GOD I SO WANT MY PERIOD TO START IT'S GOING TO BE SO FREAKING COOL". And you talked about it with your friends, and you thought about it constantly, and it was this major obsession (I think we have purposefully moved in this direction, culturally, because so many women pre-1950s never talked about it AT ALL and were kind of confused when it hit). And then it happened. Like, say, while you were walking home from school in the rain after a completely dismal day that included chocolate cravings so intense you spent all your lunch money on See's candy bars. You know, just as an example. And suddenly it was like "Oh. Crap. Well. You mean I have to do this, now? For, like... ever? Fuck."
And while I wouldn't say anything ballet-related (and therefore fun) is exactly like that, let's say I do see the similarities.
