Friend 1: Hey Cindy, what are you plans for the holiday tomorrow?
Cindy: Well, I'm going to replace the wax seal on the base of my toilet.
Friend 1: How do you do that? Just put it around the bottom?
Cindy: Not exactly. You see, first I've got to go to the hardware store to get myself a hacksaw. Then, after hacking and sawing off the bolts that hold the toilet onto the floor, I'll pick the toilet up and flip it upside down. I'll put the wax seal on the bottom, grab the toilet and flip it back right-side up, and put it back in place. And, that's basically it.
Friend 1: Um, okay. I hope I don't get a phone call from the elder's quorum tomorrow asking for help stopping a major flood in your house.
Cindy: Oh, I don't think that'll be a problem. It's more likely that I'll accidentally hack a limb off or get crushed by the toilet when I try to flip it over.
Friend 2: Can I come watch!?! I mean, help?
