I don't really follow people's relationships on Facebook, but I know these relationships never last long, and afterwards everyone seems so bitter towards their exes. That's why I don't want to start dating yet.
What annoys me even more, though, are the people (mostly girls) who go on and make these nasty indirect status updates, usually about an ex. But then when a friend comments, "PM me", they're all happy again. 
Nowadays I mainly go on Facebook to follow special interest pages (mainly Touhou related) and PM my friends from high school.

I'm sailing across Spectrum Sea, in my little boat.
The waters of the port were choppy. After I set off, there was a long, massive storm.
Years later, however, the sea calmed. I'm still on tranquil sea, but I'll never reach the Neurotypical Beach.
