Oh what a laugh! It's the first time I've visited this thread and I should have done it much sooner, because it is so reassuring to know that other people do really daft things too. I have done many of the things cited on here; but the one my daughter is in hoots about is the time I spent ages trying to get the key to work in my car after leaving the supermarket. Eventually I was ready to call the AA when my daughter joined me and pointed out that it actually wasn't my car - just a similar one.
