Why doesn't it hurt when you cut your hair, but it does when you cut your finger?

Answer: Fingers have feelings. Sometimes they are happy (thumbs up). Sometimes they are sad (thumbs down). Sometimes they are angry (the "middle finger"). So it hurts when they are cut, and fingers also show their emotions by bleeding. Hair, on the other hand, has no feelings. It does not care about you. For instance, it doesn't care that you are in a hurry to get to work -- it will still do whatever it wants. It can be messy, uncooperative, dirty. It falls out wherever it wants. It gets in your eyes. It simply doesn't care about anything. So, you can do whatever you want to it: tease it, blow hot air on it, shave it, die it, curl it, straighten it. It won't hurt its feelings because hair will always do what it wants to anyway -- no matter how you cut it.
