I will mostly refrain from any judgment. But I felt very, very alien, probably because my European ear was somewhat stressed with rhythm-rich but melodyless music. And at some point the party became somewhat more of a mating ceremony which, for me, was a good time to leave. Afterwards, the friend who originally invited me was telling that it got even weirder, and I am still unsure if I really want to know details on that matter. Probably no.
Today a roommate of a friend had a birthday party. So I witnessed what an African birthday party looks like.
