My landlord is an artist.

That is to say, he's forever daubing pictures which nobody buys.

I've come to the conclusion that most people dislike Cornwall because of the number of bad pictures which are painted here.

You see some samples of my host's brush on these walls.

They are actually too bad to be admitted to the Academy.
My poor host and hostess, being unable to make ends meet, were obliged to take in lodgers.
