Andy and K-Mart
Of course applying Andy!logic to any situation was potentially disastrous. If something didn't get broken, someone was probably going to get hurt. Andy knew it was a very real possibility, but he wasn't listening to the logical part of his brain. He was trying to shut that side of his thinking up.
He didn't often get upset or start thinking negatively, but it was never good when he did. So he was trying to distract himself. Running was definitely a distraction. He was so focused on the task that he didn't even bother to get his coat, but headed for the door to go outside.
