Be Alert But Not Alarmed

The other day 59 blipped a 2020 calendar on her fridge to demonstrate how long since she had cleaned it. 
Well this is still on my fridge. It's the information sheet Australians were given after the 9/11 attacks in 2001, advising us to be "Alert but not Alarmed" in the face of a terrorist threat.
It's not the oldest thing there. I also have the fridge magnet photos of my kids taken when they were at pre-school. The oldest recently turned 40. (He's the one with the bad handwriting who filled this in).

I don't necessarily think it's silly to not clean the fridge but some might so I'll tag for Admirer's Silly Saturday, hosted this month by KangaZu.
