I constantly try to crack my fingers even if I know it won’t do anything. I sometimes start snapping randomly too, it’s kind of weird.
I used to have the cracking fingers problem but I got rid of it somehow, now I only feel like cracking my fingers when someone else just did it.
I used to automatically scoff at mac users. But now, because of what Valve have done, I am starting to regard Apple customers as people too.
I started doing that in situations that made me nervous, and now its like an addiction, i cant avoid doing it every time that i can.
If someone tries to insult me with something that implies they had sex with my mom I respond with “Dude, that’s just gross. You’re messed up.” And I work that angle until they regret it.
Anyone I’m sat with in the pub has to have their drink on a beer mat. Dunno why. There’s some people who sit there and tear them up, which causes me unbelievable amounts of anger 
I also open the fridge frequently when I’m in the kitchen, who knows, maybe something new has just grown.:3
EDIT:
There are two outlets in the wall in my kitchen, one is used by a little lamp, the other one is for a kettle. When I want to make some toast or eggs, I pull one of the plugs out. Usually it’s the one of the lamp. And when I boil eggs or toast something at night I, as usual, pull the lamp plug, just to stand in the dark and say to myself “Oh crap, I did it again”.
I open the fridge once and I know there’s nothing there, no need to open it again for a while.
i open the fridge every time, knowing that it’s hinge is broken.
I snap my fingers when I can. I really need to unlearn it before I permanently fuck up my finger-bones or whatever you call them.
It actually does no harm at all. You just press the air out of your joints.
Really? Woow I feel really relieved now! 
You can get arthritis from cracking your knuckles too often.
lolwut?
Yeah I only crack my fingers and never my knuckles.
Hahaha, same here. And I’m supposed to speak English in a formal fashion, with Uni classes and all that… But it’s, like, I-AH DAMNIT
I’m meticulous about my spelling and punctuation with almost everything I do on the internet. Even in places that frown upon correctness or just don’t care. Even when chatting in games, I’ll spell out every word, capitalize, correct my spelling and punctuate (as best as I can, anyway). FF’s spell-checker is one of my best friends
When posting more than one sentence in a forum, I generally “preview” at least one time… most of the time I’ll change and preview at least 5-10 times before I post.
Another thing I constantly do - when someone tells me a story or I read something in a forum, I have an overwhelming need to share a story or anecdote relative to my own situation.
(I’m going to post this in a quick reply without previewing - I feel kind of annoyed at the thought)
This.
Oh my god I totally like, you know like totally yeah!
I read sentences like that in an American accent.
When browsing the internet, whenever I navigate to a new page, I always hit my home button to go to my google homepage before going to my bookmarks. Strange habit, I don’t do it 100% of the time because I catch myself sometimes.
