I also laughed at your thread title!

I do believe that the others gave good advice. However, I have come to a different conclusion for myself. I am now living with 2 adult sons, 26 and 22 years old.

They go out and sometimes don't come home until the next afternoon. I used to get upset. Now I just assume that it means they parked the car because they were having a few beers. And I am usually right.

I don't wait up anymore. I expect them to behave as adults. I don't do their laundry and I don't cook for them every night. If they are home when I am cooking then fine, but if not I don't hunt them down. I only worry about meals for my husband, me and my 14 year old.

This is a liberating experience. And it's funny because my 22 yo is calling me all the time now!
