A Common Greek Proverb

Δώσε θάρρος στο χωριάτη, ν'ανεβεί και στο κρεβάτι!

Dhose tharros sto horiati, n'anevei kai sto krevati!

See one explanation here (in Greek)

A rather more graphic version of "Familiarity breeds contempt"; literally,

"Give encouragement to (or, Be overfamiliar with) a villager, and he'll climb into your bed"
