You were lucky :)

Last evening on the metro there were three ...hmmm ... mature ... people singing. They were one man and two women and they talked a lot and loudly and at one moment the man took out some kind of a paper from his bag and they all sang a couple of lines while at the same time passionately discussing how it is supposed to be ... hmmm... performed.

Really I am kind of used to loud teenagers screaming and ocasionally giggling on the metro, but that was too much for me.

btw, "lilia" seems to be spam
