Phoned brother-in-law. Discovered lovely nephew has separated from wife. Must let him know how sorry I am, but don't have his email or phone number. Have idea. Facebook! Message nephew on Facebook saying I'm thinking of him etc etc. So far, so good.
Five minutes later, frantic phone call from daughter:
"MUM! DO YOU REALISE YOU'VE JUST POSTED ALL ABOUT M'S PROBLEMS ON HIS FACEBOOK WALL WHERE EVERYONE CAN SEE IT?"
Oops. Back to Facebook, and daughter talks me through deleting my message, which wasn't a message but had now morphed into a news bulletin.
Gave thanks that I have a daughter who wastes as much time on Facebook as I do blogging.
Went to bed, where I (probably) couldn't do any more harm.
