Ted, Dolores and Mary Jane all went out to look for some food or water since it was slowly running out. They had you as a baby sitter for Timmy, since he was slowly going crazy and was too hurt to leave the bunker on his own or with the others. The first few hours were way too silent, so you decided to break it... or atleast wanted to.

The poor 10 year old kid was indeed losing it, and as much as anyone tried to deny it, he was almost looking rabbid at this point. But you couldn't blame him, since he was always a hyper active kid, who was now stuck in a bunker due to a nuke bomb...
