Living with Bob and "Al"

Sheri sometimes forgets just how cognitively impaired Bob really is. Sheri was cleaning out some kitchen drawers and came across about 5 small electric cords that go to small appliances. Bob used to be very particular about cords like these, always winding them up neatly and putting a tie around them to keep the cords untangled. Bob was bored while Sheri was cleaning so she handed the cords to Bob and asked him to wind them individually and put a tie around them. Sheri was surprised that "Al" was not able to accomplish this. When he started out it appeared he could do it. That lasted a few short minutes. "Al" would pick up one, put it down pick up the same one, and so forth and so on. Then he started to try to attach random cords together to find a way to plug them into each other, then put them all in a bag and then poured them back out in his lap and started over again. Such a simple task for Bob "the build anything, fix anything hardware guy" but totally impossible for "Al".
Such a very sad disease.
