Is there a magic age that you reach to become an adult, when polled the average answer was 26 for men, and 23 for women.  Some of the signs you've reached adulthood include .

1.  Having a budget.

2.  Buying a house.

3.  Investing in a 401k.

The other things that make you realize you are on your own . . doctor visits . . . shopping for groceries . . . and cooking dinner most nights

“Part of the process of adulting is realizing you no longer have parents telling you what to do, where to be, or what to eat … so suddenly you realize you’re in charge of your own life and for some, that can be a strange feeling.”

I actually thought you became an adult when you stopped eating Spaghetti-o's and chicken nuggets for dinner.
