Spelling

The other day Little Man (who is 4) and I were walking to school and bumped into a neighbor.  She asked him if he knew how to spell "Go".  He just looked at her, then she asked if he could spell his name, and he did.  

Then she asked him to spell 'Mom".  He answered "M O M".  Then she asked him if he could spell it backwards, he looked at her for a minute.  

I said, "That seems a little tricky, but it's the same backwards and forwards"

He replied, "Oh yeah, it's a palindrome"  Neighbor's jaw dropped
