I will explain why I always pick the people:
1) Mike
2) Liam
3) Lily
4) Bill
I picked those names since they are nice and short, and they came to my mind first. There, I just explained why I chose those names.
Example:
Mike: What's it like to have a dishwasher? Explain to me why it's so nice to have, and why I should spend my money on one.
Liam: Well,
first off, you don't have to hand clean dishes, it does it for you. Also, it usually gets all the stuff off.
Mike: Explain why it's easier than
hand washing stuff.
Liam:
First off, you just have to put the dishes in, select the settings, start it, and enjoy life for the few hours you have before having to put them away.
Mike: Oh. Sounds like it's pretty easy, I'll get one tomorrow!
