This week,
3great_hermes has a bad idea challenge for you entitled "He thought it was a good idea at the time, but it really really wasn't."
Your mission is to write about a mistake, but an honest mistake. Your character thinks he's doing something good, but he's actually not. Silly mistake or tragic mistake... major or minor... however you'd like to present it, someone's good intentions go down the toilet.
You have 70 minutes.
