There's a very funny looking, very jolly plumber in my house. I'm the only one around, and am not quite sure whether you should follow them around, nodding politely at what they say, or leave them be and hope they don't steal anything.

This makes me sound asthough i'm worried that the plumber is up to something - i don't, he's a lovely chap with a london accent. I'm just not sure if its rude to go and leave him, like im doing now :)
