Why does the moon keep following us?

One of the workers at the laser lab told me this today while I was waiting for the laser machine to finish cutting my project.  I was cutting out crescent shaped moons out of plywood and he looked over and said, “Oh, is that a moon? I love moons.  When I was a little kid, my mom took night classes so she had to take me with her.  And I remember asking her while she was driving, ‘Why does the moon keep following us?’  And because I used to get really scared of the dark and going out at night, she replied, ‘It is because the moon is protecting us’.”

I don’t know why I find that so touching. Moms are the best.
