I've said it so many times, there is a level of expat society there that is obsessed by everyone else's lives and movements. It takes over their entire personality and entire life. What you wear, drive, drink, who you are seen with, who you aren't seen with, anything and everything is fair game. They will discuss anyone at all with anyone at all, even with complete and absolute strangers. They are your enemies, they are people you thought might be your friends and they are people you have never spoken to in your entire life, but they are an authority on the subject of you.
Even your closest 'friends' are often unlike the friends you had in the UK - I recall two couples having a meal together, both enjoying the company of the other pair and sharing a lovely Turkish evening. Much affection shown when one couple eventually called it a night. Then before they were entirely out of sight, the wife of the remaining couple was telling staff "see her, she drinks her Bacardi at home but when she's out she'll only pay for Efes"...
When you live there, your private life is, sadly, stolen and pulled apart by these people. They don't have to know you at all - it's a cliche but what they don't know they make up. When you confront them about it, they blame someone else. Normally one of their friends.
