How can you like them if you do not know them?
In this era of Facebook™, the meaning of "friends" includes people about whom one may have no more than the barest awareness of their existence. I have no idea who about 180 of these people are:
There could be serial killers in the mix. I dunno, but die Eule categorizes them as my "friends" and I actually have no say in the matter.
It's an interesting world we live in.
English had a similar thing, and it still remains in short phrases and special usage:
"She loves me, She loves me not."
There was a slight revival of the usage, maybe late 90s, where someone (usually a comedian) would append a "not" to the end of a sentence to change it's meaning abruptly:
"You are the most amazing person I've ever met -- not!"
