DO YOU SEE THE PROBLEM IN THIS PICTURE?

I see them all...

1.) My sister at my desk

2.) My son writing on my pretty paper on my desk

3.) My nephew

4.) My daughter

Now the rule is "DONT GO IN MY ROOM"

Well I'll just be dam..They love my room and love to sneak in when I nap, or I cant hear them sneak in there. There are plenty of other rooms in this house..but for some reason they take over mine. I am finding notes that say.."Mother I am the best daughter"...or a candy wrapper..my collection of note cards all of the place. What more can I do..Put traps down?

*I am being funny I dont really mind them being in there...
