Strops - you are not alone - I find the idea of having people round stressful. I wouldn't have anyone for dinner for about a year after we bought this house, because of the ever-present renovations (whereas, in fact, our friends wouldn't have given a toss about a bit of mess/disorganisation). And our old house was too small, particularly where little people were involved. I just like it all to be "perfect"when I'm hosting, and worry it won't be; I feel that I will be judged and found wanting, even though that is irrational bollocks.
DH is always keen to invite people round, but as he doesn't cook or do the cleaning he can't see what the problem is. Wafting around pouring wine is pretty stress-free, it would seem. 
Of course, whenever I do bite the bullet and entertain I have a great time and wonder why I don't do it more often. 
Anyway, DH has departed for a week in Berlin, which means I'm in sole charge of child-wrangling for the next few days. I've just been doing battle with the sticky-back-plastic for DD1's homework; her art book now has more wrinkles than my forehead, and that's saying something.
Get well soon, Ruby.
