I would ask him in base58Check:

"2KXYNwUtqEUxsAviu5gcuJrU8BsFHD6NGQRLgxe" --> translation: "How are you doing pleb?"

and... if he answers...

"24pk2DkLxbr2AiCF1Pse1UEjBTHqXz2wrRXvyKdpvopvdQUcWbimDa6kzAmUzjcL2" --> translation: "All good here, I keep stacking sats humbly"

...I'll get the confirmation that my supposition was correct... ...don't suppose, verify!
