Where the H... is your cup?????

Ok, so around this house things get lost.  TOO often.  and cups drive me crazy... C-R-A-Z-Y!   someone recently gave me a brilliant idea.  and it's working, somewhat....  I painted over an old small chalkboard (a cutting board would work too).  I put our names on it.  I have it in a central location by the fridge.  The kids are supposed to put their cups on their names when they are not using it.  they are pretty good about it.  Not perfect, but hey, bad habits have developed over years... they aren't going to change instantly.  Anyway, here is the picture of it (sans cups)
