I am so trying to find a creative way to make my son remember to take out the trash.  I'm wondering if it's just a man thing, a generational thing because I remember hearing my grandmother and my mom fuss about it.  Now it is my turn and I'm so over it.

Well, he's 20 almost 21 now and I thought that as he grew older it would become automatic.  I don't want his potential wife to be frustrated by what should be automatic.
