ELI5: Why does rain not hurt when it hits you, even though it falls from an average height of 2 kilometers (around 6500 feet)?

I was wondering why rain doesn't hurt when it falls on you from such a large height. I was thinking if I were to drop other objects of equal size from this same distance it would definitely hurt.

Thank you!

every object falling through the air has a terminal velocity based upon air density, object density, and frictional forces. 

A drop of water weighs so little, and falls through the air at relatively low speeds, that it hardly has any force behind it at all.
