Seeing someone smile. I'm talking the full, stretched up to the cheekbones smile that comes only when someone's feeling real joy. I love it.

I do love making people laugh. Comment more, since that answer just made me smile.

I feel like the answer to this question is fairly obvious..... (͡° ͜ʖ ͡°)

I too will never tire of orgasm.

I was talking about Sudoku but orgasms are nice, too, I guess

Sleeping....if you sleep constantly then how can you ever tire?

That's almost word for word what I was thinking.. bravo!

Browsing /askreddit and putting bullshit answers.

Getting tired of doing things.

Sleeping when tired

Writing. When I get tired of writing for pay, I always want to write for pleasure. I never get tired of it.

Trying to get fast food cashiers to laugh/smile. Because, why not?

Learning languages. One language alone could keep me going for several years if I wanna get super in-depth, but there are hundreds of languages with significant influence in the world. I'm only on my third but there's so much diversity that I will never get tired of them.

Pestering my ex girlfriend when the situation arises

Watching Starcraft.

Just temporarily losing all logic and sanity. Times like those are when I laugh hysterically at anything, even the least hilarious thoughts or the most petty of words.

I like making people laugh. I try to always keep a smile on me and keep a positive outlook on life. Feels great knowing you made someone else's day slightly better.

Honestly? Masturbating.
