Would these be some sort of OCD?
(1) When walking down the street having to try and get both your feet to step on the same amount of surfaces the same number of times, so you meander across the pavements, put in extra steps, smaller steps, larger steps etc just so you step on one colour tarmac the same number of times with each foot, or can step on the curb at one side of the road with one foot and on the curb at the other side with the other foot for example.
(2) Counting things in a room like
(a) the number of opening (an opening being a door, drawer, window, cupboard draw, CD drive on a computer, Floppy drive on a computer, CD or tape opening on a CD player etc....)
(b) counting the number of walls, pieces of skirting board, floor, ceilings and unremovable fittings like plug sockets, light switches, windows and radiators
(c) counting the number of pieces of furniture in a room and if the total number isn't a 'nice' number (what ever a 'nice' number is - it can vary, but is usually even, often also divisible by 4 or 10 as well) having to start again by including new things in the list (like the collection of things on top of a surface could be classed as 'one' in the count, maybe 'two' if there is a lot of stuff there and an extra number or two is needed.
(3) having to do or say things a given number of times, normally in sets of two or 4 and sometimes having to do things multiple time a number of times. Like maybe counting the 4 squares on a board 4 times, then repeating that process 4 times in total before you can move on.
