Do you still live with your parents?

Why does everyone give anyone over 20 a hard time when they say they still live at home? For me, I moved away for 2 years and moved back home after finishing college. I'm turning 23 next month and live at home and dont really pay for anything. My mom doesn't charge me rent, food, utilies or anything. I can't afford a house but I'm starting to save for one. I can afford rent but it is ridicously high in Southern Cali. So what's is the problem? Should I move out or stay at home? Whats the maximum age until its weird?

The only issue I see is when you tell a girl you live with your parents or when you try to bring a girl home; it can be embarssing, other than that living at home FTMFW!
