if someone ask me: "Have you ever been in jail?"
and I was in Jail for XXX days/years etc. , how do I have to answer when I'm at the moment of speaking not in jail ?
a) Yes, I have been in jail once for XXX days/years. -> (I think thats wrong because it's an finished action !? )
b) Yes, I was in prison for XXX years, days etc.
Sometimes it's confusing.
