You know you're an adult when you go to the doctor's office fearing not getting a shot or the doctor himself, but the bills.
If you can relate, you'll love these illustrations by Dave Mercier of MercWorks. Titled 'Childhood Fears vs. Adult Fears', the artist posted the illustrations to College Humor and we couldn't resist showing them to you. Not only are they hilarious, but they're completely relatable too! Take a look below and vote for your favorites.
