At school my French teacher used to say that if a French person saw our store-front windows with SALE all over them in January, they might think they were all dirty!
This sprung to mind one January while looking at the local department store windows, 500 miles from where I grew up, and lo and behold there appeared my French teacher and her boyfriend. I hadn't seen her for 10 years or so, and it was a lovely moment, but when I told her I'd just brought her story to mind in that moment, she did look at me strangely.
I like Kate Bush's song 'Strange Phenomena' - sums it up for me.
