Sometimes you meet people you don’t know. Sometimes sometimes is in an elevator. Some of these people might be neighbors. Some of them you’ll never see again. While spending time with these people in an elevator you might get some of the most basic information about these people you can get:

1. How they breath.
2. The volume of their speech.
3. Where they look at when there’s nothing to look at.
4. Their shoes.
5. The content of their shopping bags.
6. Type A pushes the button immediately, Type B asks if you wanna do that first, Type C asks where you have to go and then pushes the button for you.
7. Their kids.
8. Their goodbyes.
