I bet you a souvlaki with all the trimmings that your friends name is Haralampos Haralambous and that he is a Greek Cypriot :)
Actually the names
Petros (
Peter) and
Pavlos (
Paul) share the same name day as
Apostolos, being all JC's Apostles!
The funniest case of Greeks I know who have reluctantly adopted "user-friendly" names is a friend called Triantafyllos. He works at an international company in Athens, and allows foreign colleagues 'n' customers to call him
Frank. We all make sure to incessantly pester him about that :)
