I thought it was mean of O to test his father like that. He comes on Laertes, alone, shabby, dirty, and sorrowful, and is moved.
"Odysseus, who had borne much, saw him like this,
Worn with age and a grieving heart,
And wept as he watched from the pear tree's shade.
He thought it over. Should he just throw his arms
Around his father, kiss him and tell him all he had done,
And how he'd returned to his homeland again--
Or should he question him and feel him out first?
Better that way he thought, to feel him out first
With a few pointed remarks...."
What's to feel out? He knows from Telemachus all that's gone on, he can see his father's grief, but off he goes into another long rigmarole. And as you point out, Frybabe, it isn't even much of a test.
