Two Girls Reading

I framed a print of Two Girls Reading by Renoir and hung it in the dining room. I had bought two of these prints with the idea of giving one to each of my daughters - but the time never seemed right. I happened to buy the prints at the Los Angeles County Museum of Art 15 to 20 years ago, on a Sunday afternoon, after a docent talk where we stopped by this painting and the docent read "Ballade Of Lost Objects" by Phyllis McGinley (below are the last three verses). It made me think of my girls growing up so fast. And now I think of my four granddaughters.
=====
This is the house I used to share with
Girls in pinafores, shier than does.
I can recall how they climbed my stair with
Gales of giggles, on their tiptoes.
Last seen wearing both braids and bows
(But looking rather Raggedy Annish),
When they departed nobody knows --
Where in the world did the children vanish?

Two tall strangers, now, I must bear with,
Decked in my personal furbelows,
Raiding the larder, rending the air with,
Gossip and terrible radios.
Neither my friends nor quite my foes,
Alien, beautiful, stern, and clannish,
Here they dwell, while wonder grows:
Where in the world did the children vanish?

Prince, I warn you, under the rose,
Time is the thief you cannot banish.
These are my daughters, I suppose.
But where in the world did the children vanish?
