Sign that I am possibly becoming an 'adult':
I went grocery shopping last night and made two impulse purchases. A bag of sugar snap peas, and a box of cookies. Part of the motivation for this was the fact that I was hungry. So, on the way home, I decided to have a snack. In the past, I've gone right for the cookies. Last night? I ended up eating half of the peas.
I did, however, put some of the cookies in with my lunch today.
