How do you address to people?

[Milika]

How do you address to people of different ages around you if you don't know their names? It's very  interesting to know for we all are from different places!

[Vaire]

In english or russian language?

[Mousee]

All unknown people and my students I address formally like "You", but I can address my friends even by their surname.

[KishMishsh]

In my town people say "man!"(muzhchina) or "woman!"(zhensh'ina) I never address to unknown people in such a way... I usually say "Exuse me..."

But I think that's it's a real problem.
