Crying Tears of Joy

My children have called me the "rock" (not to be confused with Dwayne Johnson) because I don't cry easily. I grew up thinking that crying was a sign of being a victim and feeling sorry for myself. As an adult, I now understand that there are different kinds of tears. The kind that I want to foster in myself are an expression of sadness or joy. 

I think I've got the joy kind of tears down pat. This morning, I clicked on a youtube video that had me sobbing and smiling at the same time. My heart did a little happy happy joy joy dance in my chest as I watched this: KarmaTube: Sound of Music Train Station.

I don't want to ruin it for you, so I will just say please watch it and let me know what you think.
