There are many types of people that you encounter on a plane; here are just a few of those types of people...
1. The screaming child.
2. The crying baby.
3. The "I'm afraid of flying" Person.
4. The little kid that wears a life jacket (yes this has happened to me, I have witnessed this).
5. The "know everything in the safety packet" person.
6. The person that dresses for the runway.
7. The hot guy you will never see again.
8. The person that takes up all of YOUR arm rest.
9. The guy that falls asleep on your shoulder.
10. The old couple that is just way to invested in what is going on in your life.
11. The college kid.
Those are just a few of the types of people you meet, and I'm sure there are plenty more that haven't been named but you get the point.
