for a coincidence

Last night in Vancouver, we were walking back to Chinatown under an expressway, in a rather uninspiring section of town. Waiting at a cross-light with another couple on the other side. As we crossed the street I glanced at the man and noticed his Chamonix North Face tee-shirt. He happened to do the same and… noticed my identical Chamonix North Face tee-shirt! We shared a laugh at this (huge?) coincidence and continued on our respective ways. (He was not taking part in MCMskiii in case this seems a likely explanation!)
