Don't text him back! Maybe it's my American paranoia knckiig in, but when I lived in the Middle East, men would spend hours calling every combination of numbers they could think of, waiting for a girl to pick up. Once they found one they would call as often as they could, like 20 times a day. It happened to me several times, luckily my lack of Arabic usually threw them off enough.Although, I'm sure Italian men might not be as stalker-ish as Arab men.
