My superpower has got to be pushing things off and screwing myself over in the process, despite knowing better.
Yesterday for example. My house has an issue every winter with a certain section of water pipe in the basement freezing when it gets cold. I knew saturday night it was going down to -30c (-22f) with a -41 windchill overnight but I still neglected to toss a space heater down in that spot to keep it warm overnight.
Lo and behold first thing in the morning I wake up to no running water. So I had find where my propane torch was, just to spend half an hour running around with it to thaw the lines out before I could even make coffee or properly flush the toilet.
At least now I have a space heater running down there to keep it warm again, like I did last winter, and the winter before that.
