Apparently, gopher is still a thing.

1. Nothing. I neither grew up with Halloween nor ever dressed up much at all.
2. No, but my grandparents learned what it was like to live under Nazi occupation in WWII.
3. Learning languages. For example: Japanese self-studied, Russian at university.
4. Probably some piece of music that I then decided I didn't like and deleted. I am a piano/keyboard person.
5. Life! Technology a close second.
