Your father decided to go out and send a mail. It so happens that he enjoys sending mail for real and not through the internet as everybody else insists on doing these days. He is simply too practical and creative for that. He is not back yet, so there is really no point in worrying about him at the moment.
Not that you know that, of course.
==> Carry on. Without worrying about Dad too much.
Gavin I mean the brother that you do not know, does not seem to be bored of his exotic magazine yet. The toilet also happens to be a pretty good place for reading such a thing.
==> Better let him... take his time and keep focusing on Vieve instead.
