Bossy Bella

We have electric heaters in each of the girl's rooms (we do not have central heat and air - just a window A/C unit in the living room [which can also function as a heater], a window A/C unit in our bedroom, and a gas heater in the living room). Last night, Brannon was checking the heaters to be sure that they were turning on at the right time (he has them set on a timer, but I sometimes turn them on at naptime and consequently screw up the timers). He checked Brooklyn's and then closed her door so her room could warm up. He then proceeded to Bella's room, where he checked her heater and then tried to close her door. She stood in the "hallway", pointing at him saying "no close door, no close door" in a very serious, bossy voice! She then pulled him by his shirt back to the living room to the couch and told him to sit down! We all know that laughing at them when they do these things only encourages such behavior in the future - but tell me how are we not supposed to laugh! It was soooo funny!
