Ooo yes, QQ, add me to the PM list so I know where I'm going. Are you in the part of London marked on maps with "Here Be Dragons"? 
Hattie - a sherry schooner is an extra large glass. A double, I guess.
The hot water cylinder is all done, and all plumbing is functioning as it should; there was a slight panic when the plumber noticed that the cold water tank in the loft was effectively balancing on a couple of toothpicks and a drawing pin, so we had to ask the fencing guy for a couple of old fence posts and do a bit of remedial carpentry half way through the day.
The fencing guy we nicknamed Fungus because he was moving so blooming slowly; he is coming back tomorrow and still has loads to do.
Anyway, must attend to knackered DH who has just got home from a day trip to Germany (he left the house at 4am).
