And sure you will probably succumb to another runny nose virus, because there remain 300 different cold viruses. However you will certainly unlikely get the very same cold virus that you had before because you have developed resistance to that virus.

Parents have already had a lot of the runny nose viruses. Parents have actually established resistance to the viruses they have had. So there are not quite as many cold infections around for parents to catch. That is why parents only get infected with a couple of runny noses per year and kids usually get 10-12 colds each year.
