As best I understand it

If you get together with your friends in an online game, cooperating in a team environment to complete a challenge, that's weird.

If you get together with friends and silently watch that latest reality TV show, which you know from the credits has writers, that's normal.


If you dress up as an imaginary character, go to a friend's house and play a role playing game, essentially an elaborate improv exercise, that's weird.

If you dress up in a football player's jersey to show emotional support for a guy who makes several times what you do, simply because he got hired by a team that's headquartered somewhere near your home, that's normal.


If you spend a few weeks practicing a rhythm-based video game so that you and your friends can interactively listen to music, that's weird.*

If you spend years of your life honing your skills at a real instrument that you never play publicly, that's normal.


If you read a book about ethereal beings with superhuman powers who struggle in a battle of good and evil, that's weird.

If you're Catholic, that's normal.


If you travel across the country to attend a video game expo, where you sped several days trying out unreleased titles, playing in free tournaments, and enjoying free concerts with thousands of other people, that's weird.*

If you travel across the country to attend a convention for a job that you don't like, that's normal.


If you write your thoughts onto a blog, where the people you know can read and respond to them, that's weird.

If you write your thoughts into a journal or diary that you never show to anyone, that's normal.

*Not to mention going to the hardware store so you can get something to modify your pretend-guitar, just so you won't accidentally hit the "Playstation" button anymore.
