WHY must you kick

It seems like nearly every time I fly, I am in front of a child or in front of a person with very long legs.

Because every time, I get kicked in the back. Sometimes it’s by accident, so I wait til the third time.

Depending on how nice they look, it might be a simple, please stop kicking or if they look mean, I’ve resorted to telling them I have just had surgery.

How do you deal with annoying passengers to try to have an enjoyable flight?
