We're all carrying the virus and it is dormant until our immune system gets overwhelmed by it. I think the mechanism of "catching" a cold is under some debate, but I suspect the carrier has built up a huge population of virus and every drop of snot has billions more viruses than usual so maybe enough to tip the scales in favor of the virus.
