I wouldn't say that every girl. But those who don't want to participate in this tradition simply won't open their door.
Of course that there is not any obligation to open, but i cant remember at any case of closed doors. It is quite different in cities or country side. In country side, in villages, most people knows each other, so you can knock almost to every doors. In cities, you visit your classmates, girlfriends, girlfriends of friends, their mothers and sister, family, teachers. Fathers sometimes open doors silently and let us to whipe their daugther unexpectedly.
The major problem was on high school, because we had to plan our route precisely, to avoid visitation of our teachers in noticeable drunk state.
Lol!
I mean, that was trolling, right? You can't be serious.
It had its own purpose, maybe it still has. Father has overview about his daughter's suitors or boyfriend, so he can preemtively intervene. = This is not of course the origin of the tradition, but i and my friends observed it
