Highway 81; I can't wait to be 20

I paused to realize this morning:
Things to be done before turning 20-
Thing I must think about when I am 20-
What a small age, a single turn of the clock, 20:
And how like dying 20 will never be - except now.
When I am twenty i must think seriously about smiling only when neccessary - smiling deepens wrinkles, you know.
When I am twenty, I probably won't dye my hair purple.
When I am twenty, I should already know how to run a dishwasher, and which exit to take to get home.
When I am twenty, I can't ask for a lollipop when i visit the bank.
When I am twenty, I can't ride in shopping carts ( but probably will anyway).
When I am twenty, I will wonder why people still ask me if I'm shy.
When I am twenty, I will curse at the clerk who asks if I have parents' permission to watch R rated films.
When I am twenty, I will say what I mean, and mean it.
When I am twenty, survival won't seem like such a hazy thing.
When I am twenty, I can say, "When I was a teen..."
When I am twenty, I must practice moderate drinking so when i'm 21 it will already be boring
When I am twenty, I can say, "your music is too loud."
When I am twenty, I will be the youngest adult I know.
When I am twenty, the world will be new before me.

When I am twenty, I will be able to take a shower without flooding the bathroom.
When I am twenty, I won't be afraid to disagree.
When I am twenty, winter will seem like a holiday.
When I am twenty, I will be able to look food in the eye and say no.
When I am twenty, I'll realize that birthdays aren't such a big deal.
When I am twenty, I will still ask for a pony for my birthday.
When I am twenty, I'll realize that what I really want is a new pair of shoes.
When I am twenty, I will probably buy and new pair of shoes because these shoes are starting to get holes in them, and they're turning green.
When I am twenty, I won't need someone to tell me to clean my room, because, IT'S NOT GETTING ANY CLEANER, DAMMIT!
When I am twenty, I will be the first one not to take it seriously.
When I am twenty, I'll always call you back when I say I will.
When I am twenty, I'll know what I'm talking about.
But maybe--not just yet...
