First of all, @Monique vdB : Happy Birthday! Hope you have a fantastic year ahead 
We went slightly 'off-topic' :P
I genuinely believe that everyone is 'weird' in their own beautiful way.
I am weird to some and normal to none
Here are some of my quirks:
- I cry when I'm nervous
- When I write something, I NEED it to be formatted and edited properly before I can move on to my next sentence - which is a big no-no for a content writer, you should never write and edit at the same time. (I just did it again)
- I snort when I laugh, then laugh harder

Now, tell me about your quirks! 
P.S.: With all the seriousness around, I just think this could be a good laugh
