A lot of people will tell you that there is just something special about dogs and having one. They sense when you aren't feeling well, when you are upset, and of course know when you got food to share.
In this situation, a woman was waiting for her flight with her cute corgi at the airport. The dog let go and ran to a guy sitting quietly by himself. He just sat there patiently like they have known each other for years. Turned out the man lost his dog the night before and was just really upset about it as you would imagine. The dog somehow just magically knew that or maybe he saw the other dog as ghost watching over its owner. Who knows but it just hits your heart.
