I have had my experiences of what to do and what not to do but i still don`t seem to get a hang on it
E.g this other day i was talking to my neighbour about a problem with the laundry room, there is a foreign woman who uses my washing time and it has gotten to be a big problem. While i was complaining to her i "accidentally" blurted out a phrase the foreign woman had said to me down in the laundry room. I changed my voice to sound like her. (Oh.crimplets why do i not think before i speak?) You see the neighbour i was talking to is also a foreigner and so is the neighbour who overheard us speaking about this problem when she had her door on a jar.
So the moral must be not to speak!?
