NOTES:
*The states height will go mostly by age. I think it's a little weird for a 7(like a Alaska) to be the tallest when he didn't hit puberty. So the younger states will be short and Delaware will be the tallest.
*The states all have a roommate
*Older states tend to stay up later that younger one
*The states on not knew by the countries
*The states are related to NATO and the UN(half siblings)
*If a state has two words(like New Jersey, Rhode Island, and the Dakotas) their name will be like NJ, Rhode, and York.
*I aged some of them up in a edit
