I'm a real sap, and stuff makes me cry pretty easily. My sister told me the other day, "I cry at commercials. It's pathetic." And I'm sure I'd cry at commercials, too, if we watched TV. Since we don't, however, for me it tends to be song lyrics.
This one is a real doozy. When you go there, though, turn off the screen and just listen to the song. The video part is pretty schmaltzy.
