White Board Fun!

I have recently put a whiteboard in my office. My children enjoy it. They draw pictures, write me messages and really encourage me. They tell stories. (I didn't know Yodi had a brother or Jedi was spelled jeti ....) and mostly tell Valerie and I they love us. I have an open office policy. Anyone is welcome to visit; relax or just chew the fat. Sometimes I don't see how some church leaders can have a closed office and be so isolated. (And yes, there are times when my office door is closed but doesn't mean I don't welcome visitors) So what do you children do to encourage you?
