My wife went all goonhilly when the lady from social services telephoned this morning, following on from last week's wandering incident. Her listening in did not stop me having a conversation, after which I told an outright lie about who had been on the phone - and one which she accepted readily. It doesn't come easily to me but telling the lie was much better than having to go into the reason for the call, especially as my wife (if she even remembers) would say that it is perfectly normal to "go out for fresh air" after dark and when the temperature is heading to zero. I know this but being a liar is new to me and a skill I'll need to practice.
