Do you have any "strange" habits?

My eccentricities are :
I have to have the same colour peg on each item of clothing (eg: tshirt = 2 pegs. Both will have to be the same colour).
The dishes are washed in an order. Cups, cutlery, plates/bowls, saucepans/frypans. Or in the dishwasher - the cutlery tray has only one item of cutlery per thing. (eg: spoons in one, forks in another)
We have 4 pillows on our bed, two each. We each have a thick and a thin pillow. I have to have both thick pillows with the same pillow case, and the thins have a different one. (does that make sense?? When I made the bed the other night when this topic came up.. the thicks had a white pillow case and thins a yellow one)

I'm sure there are others. I know my mum does the pillowcase and peg thing too!
Am I weird or are there others out there??
