We have an escape artist on our hands

This morning I got in the shower before Mike left. I made sure that Will was all set up on his starfall program so that he could practice his ABC's while I was in the shower. Isaac was watching him do it. I heard Mike close the door when he left. I always leave my bedroom door open and occassionally leave my bathroom door open too (Isaac likes to try and climb in the shower so I have been closing the door lately). Anyway, I got out of the shower and thought, "Hmm, it's quiet in here. The boys usually come to see where I am when I shower. What are they doing?" I hurried and got my garments on and then heard a knock on the door so I went down the hallway and the doors were open and the boys were both outside! I saw my neighbor Max on the doorstep so I ran back to the room, grabbed Mike's robe and then came to the door. Max was like, "I saw both boys outside and I didn't see you or Mike so I wondered if everything was ok." When I told Mike about it at church he said that he had closed both doors and locked one of them. That is so scary. We live on a busy neigborhood road not a busy town road if that makes sense. What are we going to do now that Will can get out of the house? How am I going to take a shower now? It reminds me of my brother David. He used to pull chairs over to the door and get it unlocked then leave somewhere. Once he crossed a busy street to go to the church where my brother was at YM's. Another time he tried to follow my parents when they left on a date and ended up on a busy overpass. We spent hours looking for him. My mom finally got a leash for him and put hospital braclets on his wrist incase someone found him when he ran away.
