Writing has improved my social life.
Yes, that's an odd statement. No, I haven't suddenly become a famous author with people clamouring for autographs and attention.
I have, however, developed a vested interest in getting to know people, what they do, and what they're interested in. And this has the singularly large benefit of making small talk a whole lot easier, which is something I'm normally really really bad at :)
Being interested in everything has its advantages after all O:)
