When I was a kid, I can remember going to church with my grandma and watching her weep through the entire mass. I never understood it, and when I asked my mom why she cried even though she was happy, she would just say, that's how grandma is moved at church.

It took me until I was an adult to understand why tears can come from a happy moment. This baby understands already.

Watch as she is moved to tears from her mom's song.
