Here’s what I would do if I was left home alone: cook up a pepperoni or cheese pizza in the oven, watch some really neat music videos on YouTube and — last, but not least — listen to some really great music or watch some TV show episodes on my laptop using my Windows Media Player.
From my perspective, what Kevin did when he found out he was home alone seemed to be kind of cool, as well as very neat, too. :)
I was left at home by myself a lot as a teenager, never as a child. But I was never left home alone for more than a few hours. Anyways, at that time, if I was left home alone, I probably would invite my friend over, watch movies and order pizza and maybe do some baking since I've always loved baking.
