I cry every time this commercial comes on television and (every time) my 6-year-old says, “Mom, you do know it’s a commercial about Apple.  They make phones and Ipods.  Why does that make you sad?”  It’s hard to explain.  It’s the same reason I cry at the end of Toy Story 3 and while reading “Love You Forever.”  He doesn’t understand yet, but someday he will.
