Do not open that door!!!

I had a reminder today that so many of my little trials are shared by all moms.  Laci has a tendency to open the stall door on me while I am in the restroom.  But I don't want her waiting in the bathroom alone.  Today we were at lunch and Laci and I went to the restroom.  It was my turn to go and I told Laci to wait in the stall for me and reminded her "Do NOT open that door while I am going!"  I heard the lady in the stall chuckling.  I have a feeling she may have said similar things to her children in the past too.
