Depends on the person. I'm turning 26, and have never lived alone with the exception of the past 4 months. I lived with my mom until college, lived in a dorm for 4-yrs, and then lived in apartments with my girl for another year or two. Since she left me at the end of April, I've hated every minute here living alone. I need to find me a high-maintenance girl who'll move in after a few dates. ROFL. Being alone is for the birds. Sure, I like it to a degree, but take weekends for example, I get bored. I have hobbies and such but I'm just not motivated when the TV provides company. Sad I know.
