Some things make you feel very old.
While studiously wasting time this morning by poking around some newspaper sites, I came across articles about some people's astonishment at finding out what the glare-reducing tab - apparently a "secret button" - on a car's rear-view mirror is for.
Now, I like to think that I give uninformed people the benefit of the doubt -- not knowing something doesn't make a person stupid -- but my flabber was absolutely gasted to discover that there are grown adults out there who have been driving for years without knowing what the tab is for.
