Shouldn't be a > problem since you're loaded, right? Graham lives in a shed. It's bigger (I think) than the storage shed I just had built, but not as nice. Yes, he's clearly "loaded", but he would get even more loaded if he sealed up the shed and used gas in it. Better yet, Graham, seal up the shed and just open the gas valve a bit, with no flame.

You just can't get much better than a person who pretends to be rich having to go extra lengths to keep the spiders out of the shed he lives in, and dreaming of the day he can move on up to a caravan.
