I'm off to Prague tomorrow with the mother and sister. Just letting you know in case you pop in and I'm not around. Also, for future information, I hate people who just 'pop' in. I require notice of your intended visit at least two days in advance so that I can arrange to be out or fabricate a feeble excuse. I will not have my aimless pottering disturbed for anyone.
That is all. Behave yourselves, children.
