Mrs. Clean strikes again

I might get a little carried away sometimes.  I have a tendency to micromanage  the kids rooms when I absolutely can't stand looking at, or smelling, them.  I know my oldest is far too old for me to go tidying up after him, but yesterday when he left early,  I jumped at the chance to do the following in there:

*Strip the bed and clean all the linens

*Remove everything from under the bed, vacuum, and replace it all

*Hang two small shelves

*Wash all the clothing I found under the bed or on the floor

*Dust the tops of shelves, desk, and dresser

*Clean the new office chair he got from the neighbor

*Replace a bulb in his ceiling fan

*Spray the room with Oust 

*Replace the batteries in two dead clocks

It doesn't look like a lot, but it took me well over two hours.  And, I didn't even open his closet or empty his trash.  When he got home from work, I think he liked the looks of things in there.
( His room is a stormy blue, with accents of red, khaki, and navy.  His furniture is basic black.)

 I ask you:  how can my kids be so unlike me when it comes to keeping their rooms together?  How have I not taught them over the years about being organized and clean?  They have never had to contend with a messy, smelly, disorganized home - maybe when  they have their own home someday, they will hear my voice in their heads and get to work!
