What makes me feel grown:
Having my car payment debited electronically each month from my account (this is the only bill I can do this with, too scared to do the others)
Having my grandmother depend on me for errands
Funny story-My mom always said that I was grown ONLY when I moved out of her house. So when I was living there after college and had my job and car I still wasn't grown to her. When I moved out I was contemplating on when I would let her know that I was grown because she neglected to acknowledge the fact

We were at my grandmother's house so I decided to let them know at the same time. I proudly announced myself, and my mother called me over to her chair. Thinking she was going to congratulate me, this lady PUNCHED ME IN MY THIGH!!

It hurt too! I didn't care though, cuz even with a hurt thigh I was still grown

Later on that night I of course accidentally ran into the footboard of my bed and bruised the exact same spot where my mother hit me. Boo.
