There are two kinds of people - Greeks, and everyone else who desire they were Greek!
The Greek people are famous for their hospitality to foreigners. Greece is one of the few places where you may be invited for a meal but most Greeks would think it a big discourtesy, if you, as guest want to pay for the meal.
The Greek people use different movements to signify ‘yes and ‘no’, instead of the usual nodding and shaking of the head, ‘Yes’ is signalled by a slight nod of the head downwards, and ‘no’ is signaled by a small bob of the head upwards.
The Greek people are also very superstitious. Tuesday is considered very unlucky, because it is the day when Constantinople became part of the Ottoman Empire.
The Greek people do not celebrate birthday, they consider its celebrating is generaly a matter of the family.
