Visiting the Harolds

Still four days before Sam and I sail east, so we drove to Steubenville for a short visit with daughter, Rachel, son-in-law, Phil, and grandchildren, Edy and Max. These are extremely bright and charming children (as you can probably judge from the above photo (photography by Sam Durbin).
At the park this afternoon Edy decided to instruct me on the topic "plants".
"Which plants don't you know about?"
"I don't know which plants I don't know about," I answered.
"O.K., poison ivy . Wear long pants and sleeves and don't scratch when it itches."
" I see; how many leaves does it have?"
"Twenty", she stated confidently.
I suspect she'll be a science teacher or a poker player.
