sentimental: My son moved out last year. I still left his room how it was. Sometimes I go in there and look at his pictures and old trophies.

Awesome, a bird left the nest.  How old is he?

He is 20 and is now living with his fiancee and child, but I can't bring myself to clear out his room. I left it how it was.
