Um, help me!?

Dad wasn't feeling well, so Mom was going to take him home from church. In Primary, they announced that someone else would be doing the singing, cause Sister P would be gone. Nathan, age 7, stood up, and said, "That's my mom!" and out the door he went. They started a search for him, but were unable to find him. One of the Primary Presidency was walking down the hall past the handicapped bathroom. She thought to herself, "I wonder if he's in there?" She knocked on the door and hears this little "What?" She went in and found him laying on the changing table. He had climbed up, and strapped himself in, and couldn't get out!
