Do i have to grow up?

i am at a weird point in my life. i am not yet an adult, but i am not a child anymore either, i am just in the middle. And sometimes i get confused who i really want to be. but after spending a day going to the bank, getting gas, and going grocery shopping with the cart. then, getting messy by using sidewalk chalk with little kids and decorating cupcakes, its not hard to make a decision.
