How finickety are you?

So I was wondering how many people out there are fussy about little things that don’t usually bother other people?
For example:

My brother likes a tidy car and has a bin in the passenger footwell
whereas my sister lets the rubbish pile up and then has a big clear out!
Me… perhaps a little more finickety than most…when I am pegging my clothes on the washing line they all have to be straight and they absolutely all have to have the same pegs holding each item of clothing, all pink or orange (and yes I know wooden pegs would solve the problem but they leave dents in the clothes, I have non-marking pegs!) My husband takes it one step further and puts all the clothes that belong to one person on their own particular part of the washing line – it makes it easier when you collect them in they can go in the basket in order to be placed in each room accordingly!
My grandma irons hankies!
My mother in law irons all her bedding!

So what things do you have to have just right that others could probably take or leave?
