THIS is the exact stupid thing my 26 year old sister and her best friend do at my parent's place. They both live there. My sister is usually spending more time at her boyfriend's house, but still. It pisses me off. My mom is too stubborn to admit that the both of them are mooching off of her. She swears up & down they help out all the time. Whenever I go back to visit, I seem them helping eat the food and drink the soda. Not once have I ever seen them clean something up. Must be nice to have no rent, water, electricity, etc to pay.
If my husband & I lived with family (free of charge), we would easily have $30,000 in the bank. Enough to buy a house.
I'll be honest, I lived with my parents until I moved to Nebraska a couple weeks ago, and I'm 26. I get along really well with my parents, and my mom has been spending a lot of time helping with my grandfather who has Alzheimer's, so she would be gone for weeks at a time sometimes. I basically picked up the housekeeping slack while she was gone. I was able to save up quite a bit living there while I was working, and it allowed me to quit my job and finish 10 pre-requisite classes over a summer and fall semester. I had enough in savings to pay tuition and to pay for an apartment in Berkeley for a summer. I bought groceries fairly regularly, and my mom and I mostly split the cooking when she was home, and I did it when she wasn't. It worked for us. My mom said that as long as we weren't fighting, she would rather see me put money in the bank than putting it on an apartment.
My brother, on the other hand, is 22 and living at home and he sits on his rear playing video games most of the time. He doesn't have a job, and we don't know when he'll graduate from college. My parents are at the point where they are considering kicking him out.
I know that I had it pretty good, and that really did make life a lot easier for me in a lot of ways.
