I was out for a good long sweaty run in Queen Sirikit Park around 6PM one evening. The park was full of runners and joggers looping around the paved walkway which winds through.
I was in the groove and had quite forgotten time or place after 4 or 5 loops but quite suddenly I heard what sounded like the beginnings of a musical interlude coming from "somewhere". All of a sudden every single runner (99% Thai) in the place stopped on a dime ('cept me ... not getting it quite so quickly). After a few seconds I remembered and stopped as well . . . the King's anthem.

Until the anthem stopped, I and hundreds of others in my view stood there like frozen statues ... wheezing, chests heaving, sweat dripping to the pavement. Quite a surreal scene, made more so because of the great physical exertions everyone had been into just seconds before.
The anthem ended, and everyone took off as if nothing out of the ordinary had happened (and it hadn't ... the anthem keeps playing every evening.)

Cheers ...
