I like to buy/have things in odd numbers- mostly THREES.
If I'm writing something and I mess up, I have to start over on a new piece of paper.
I'm obsessed with things matching.
If I'm buying something (say a Christmas ornament) I have to look through every single one to make sure I pick out the one that is most perfect.
I also have to check multiple times to make sure I've turned things off or locked the door.
I'm obsessed with straight lines and perfection. I rearrange things over and over again until I am happy. At Christmas I had to redo (take ALL the ornaments and stuff off) the tree twice!
I refuse to buy furniture with curved lines.
I feel so weird if I don't use (somewhat) proper grammar online.. especially when it comes to capitalization and periods.
And there are SO many more..
