When did I get too old for eye shadow with glitter?

I'm standing in the bathroom trying to get ready for an appointment, playing peek-a-boo with my 8-month old who's on the bed in my bedroom. (These little moments where I stick my head out around the door opening so he can see me are meant solely to keep him from crying, but please don't tell him that). I blindly grab something out of my make-up drawer, hoping it has something I can line my eyes with, and I look down to see a semi-recent Sephora purchase with a sparkly pink and grey eye shadow. My instant reaction is giddiness, "Oooooooh . . . sparkly;" a split-second later, I'm hearing "Greensleeves" playing in my head. After all, I'm on my way to meet my oldest son's new teacher who would wonder what glittery art project I was doing earlier, not be asking me where I got the cute eyeshadow. When DID I get too old to wear this stuff? Oooh, and strawberry-flavored lip gloss . . . I guess having two children and being eh, hem, 30-something should have clued me in, but I wish someone would have told me when I transitioned out of the time in my life where it was okay to have pony tails, skirts above my knees, and, sigh . . . make-up that was more about making you feel girly and less about covering up the stuff you want to hide. "I don't remember growing older . . . "
