I put in writing, entertaining, and skydiving.

Something on the intellectual (?) front (and which I can talk about a lot ... I've done freelance journalism, I've written creatively, I blog ... plenty to discuss - and often leads to a conversation about what I like to read), something social (and again which can lead to many different conversations to do with people, friends, cooking, hosting, etiquette, etc) and then something rather out of the ordinary ... not every applicant to the job will be a licensed skydiver - so it often leads to interesting conversations!

If I was applying for a job now, I would probably also include anti-human trafficking initiatives, as it's an important part of my life.
