I've done this on other forums that I've been apart of so I thought I would try it on here. All you need to know is:

^ Answers the question.
< Tell what you're doing.
v Ask a new question.

Example:
V Who is your favorite couple on the show?

^ Tony and Ziva.
< Reading fanfiction and listening to music.
v Will you be watching NCIS:LA when it comes on?

The next person would answer that question, tell what they're doing and then ask a new question, and it would keep going from there.

NOTE:The questions do not have to be about NCIS. Ask whatever you want.
