Bo is putting in all the hours he can to get the outside jobs finished before things turn nasty. It's a cold day but clear and sunny. He and his mate are taking out one of my mother's bedroom windows so they can replace a rotten sill; he assures me he'll have it back again before nightfall.
There's a lot of noise. One of the guys is hammering, the other is using some sort of a power tool. Bo's mate wears a head set and is continually on the phone.
