Why is it thought normal in Malta to talk about yourself in the third person?

I’m trying to envisage a situation in which I say to a friend over the phone, “Daphne Caruana Galizia is going to lunch at X with Y today. Do you want to come too? But Daphne Caruana Galizia has to run a couple of errands afterwards, so we can’t be long.” Or better still: “Daphne Caruana Galizia is human. Today Daphne Caruana Galizia has a thumping headache, so being human she took a couple of Panadols.”

I’m afraid I’m going to have to bother you – Daphne Caruana Galizia is going to have to bother you – with my usual refrain: HEMM XI HADD NORMALI FIL-HAJJA PUBBLIKA TA’DAN IL-PAJJIZ?

This is from last night’s Xarabank.
