So I regularly attend an event weekly and am friends with several of the other regulars. Most people who come in are in the 40+ range, but a few of us are younger (30's). Recently, a younger guy has been coming in with his friends. We're friendly and we always greet one another with a hug (upon arrival and parting).
But today, he (mid-20's) gave me a (gentle) noogie when he walked past. I'm a bit baffled at this turn of events. I did not grow up in a noogie-giving family or neighborhood, so I don't really know the Law of the Noogie. Basically, is there noogie etiquette? Why was I noogied and what was the appropriate/desired response?
Enlighten me, eHellions, if you please.
