How Old Your Kids Are
After you take your first standardized test in high school, it’s not long before you receive brochures begging you to check out college campuses. When these pamphlets start to arrive in the mail, your postal worker can deduce that your child is around 16 or 17. And even when your kids are younger, there are other things that come in the mail—like letters from elementary schools and bills from pediatricians—that give an idea of how old your children are.
