There's this old man

There's this old uncle who lives somewhere somewhere somewhere. He's a complete stranger to you, but one day he just comes to your house and starts sweeping your lawn. He does it for a long long time, and does a much better job than your own housemaid, so you fired orang gaji in exchange for this free lawn-sweeper. Then uncle stops coming over, and you know he's still alive 'n kickin'. And no, he's not in love with your maid or anything like that.

Why do you think good ol' uncle stopped coming over?

Or should you start thinking why are you thinking about it in the first place? =P
