I mentioned that I also liked to do word search puzzles, and had a couple of books in the drawer by my bed.
"How do you do a word search?" he asked.
Oh, nice, a discussion about puzzles. I told him the first thing I did was to search the puzzle, to see if any words were apparent. Then I look for 'W' words, because that letter is easy to spot among the rest. I went on to say that next I look for double letters, especially 'O', as it stands out too.
I realized he was staring at me, with a seven year old's WTF? expression. He shook his head, in puzzlement.
"I just look for the first letter of the word," he tells me.
"Yeah, that works, too," I laughed.
End of discussion.
