Expats will understand

those who have never lived in another country, might think it a bit weird when at Christmas everyone gave everyone else Crest original formula toothpaste. The recipients were thrilled.

Why?

Crest original formula is next to impossible to find in Switzerland. Usually it is necessary to ask a US-based visitor or a US traveller to bring it back, something with weight restrictions, one doesn't like to do often.

Since we all like Crest, the thoughtfullness was appreciated. But we all had a good giggle as we opened the identical presents.

Having just squeezed the last from my old precious tube, I'm ready to start in on my Crest cache...
