Things you Should Have Done that you didn't do?

Have you ever regretted something you should have done but didn't do? I recently have. I was vacuuming on Monday and I always have to unplug the fridge so it doesn't come on when I am vacuuming and blow a fuse (yay for student housing). Well this time I forgot to plug it back in afterwards. I didn't even realize it was unplugged till a day and a half later when I wondered why the dip I had left in the fridge for 3 hours wasn't cold yet. I majorly regret this becuase the freezer thawed out and now I don't trust those microwave dinnres. Not that I could cook them anyways becuase cardboard containers don't do so well when they get wet. Just a fact.
