That was just fantastic on many levels! Those kids are so adorable that the first time I watched it, I was just laughing at their cuteness. (Oh how I would love to have those days with my sons back). But you also made valid points.
This is a great lesson in teaching using humor. Just think of people seeing this and really 'getting it', instead of some dry, pedantic explaination that only makes them feel talked down to and annoyed.
Really, good job.
