The family joke has always been that my sister loses something every time she goes out - at least now she has a mobile phone she doesn't leave her handbag, purse, shopping, umbrella, etc. in phone kiosks - now she leaves her bag hanging on her trolley at Morrisons, or on the bus.
I, on the other hand, have always been extremely organised and have never lost anything. I suppose that is why this sudden loss of memory freaked me out!
(I don't think I have severe OCD, but I have just cleaned out my under-sink cupobard and found five pairs of unopened rubber gloves.)
