Can't trust 'em. Can't get away from 'em.
Some people's hot
Some people's cold
Some people's not very
Swift to behold
Some people do it
Some see right through it
Some wear pyjamas
If only they knew it
The pyjamas people are boring me to pieces --FrankZappa
Normal People is a wide term, and any one person may to another person seem like part of Normal People, at some given point in time. It is a commonly supposed phenomenon that anyone who is part of Normal People, will leave that group once you get to know them.
