I don't expect any but the fondest grandparents to feel compelled to watch all 4+ minutes of this, but here ya go:
My favorite thing is that Sroch started making up this 'song' about one minute before I made the video. I love her attention to detail as the director, and I love Llama's ability to play along so quickly (especially the impromptu harmonies).
In case you can't tell, it's a story about 'ohr' (light) and 'choshech' (dark), who are asleep in the dark and wake up in the light, then get their babies dressed and take them to school, then bring them back and it's dark again. Enjoy!
