So we were waiting at the metro station, just an underground hall with staircases on one end and the rolled down shutters on the other. Some kiosk-like shops were scattered around, but all of them closed for the night, so it was whatever you had with you.
There was a somewhat smallish but cute girl of Go's age, speaking the Zagreb dialect of croatian, whom I helped with translation of something, who then somehow stayed engaged in conversation with us all night. There was some guy who was trying to get on with one of them, but was probably too drunk to get anywhere with it, except being as boring and annoying as a drunk youngster can be. Unfortunately, he spoke hungarian only so I had to do most of the talking, both ways. At least, he took at least an hour off the wait.
Whole night we were talking just to exchange slang. After only four years of living in separate countries, we fell out of sync. Of course, Belgrade and Zagreb kept their separate slangs since forever, but there was always some conduit between, some expressions would seep from one into the other, and at least a lot of people kept track of the other (and that of Sarajevo as well). So we were mostly working off that backlog. The common theme of this conversation was "wow! how did you say that? got to memorize that, it's hilarious!".
At 5:00 the gates opened, and we got on the metro, and arrived at the West station, and discovered that we'll have to wait for our trains for another couple of hours. We went to a nearby cakeshop and had some kind of breakfast and whatever passes for coffee there. The weird funny moment: she said her mother was Serbian, but she never had any problems. Then on the piece of paper where she left her name and phone, I saw her last name was same as one of the heads of the NDH... well, of course you didn't have any problems.
Then we parted, each to their own train. Arrived about lunchtime and, I guess, didn't do much the rest of the day. Slept it off.
