“Mistress, I dug upon your grave
To bury a bone, in case
I should be hungry near this spot
When passing on my daily trot.
I am sorry, but I quite forgot
It was your resting-place.”

What is ironic about the dog’s response to the woman in “Ah, Are You Digging on My Grave?” by Thomas Hardy?
He has actually forgotten where she is buried.


He misses her deeply and has come to see her.


He passes by her grave everyday.


He is the only one who remembers her.
