"Разбира се"
means "of course"; more cautiously — "Може би"
(maybe). You can also say "Съгласен съм"
(I agree; a woman says "Съгласна съм"
). "Точно"
also works with time: "точно в осем"
(at eight sharp). Russian speakers, careful: "конечно" is not a Bulgarian word.

Exactly!
When you fully agree, say "Точно така!"
(exactly!) or "Така е"
(that's true).

Bate and kaka
"Бате"
originally means "big brother", but it's also a friendly way to address any man a bit older than you — a taxi driver, a neighbour, a stranger in the street: "Бате, къде е спирката?"
(mate, where's the stop?).

The Sofia metro is fast, clean and easy: several lines link the centre with the suburbs and the airport.

By train
Bulgarian trains (run by БДЖ) are slow but cheap and scenic — the lines through the Iskar Gorge and the Rhodopes are beautiful.
