Sharm is full of gossips. Everybody knows everybodys business, it's just the norm out here. You've just got to learn not to get involved and steer away from it. The amount of people I've never met who've seen me about town and then requested my friendship on facebook is well into double figures, yes, it's more the Egyptians who do that to me but a number of expats know my name and what I do through word of mouth at the gossip circles!
I even had someone leaning against my car in the street once who messaged me on facebook to ask to be my friend after I'd given him a mouthful for touching my car!
