Do not use the fact that the children have 'separation anxiety' as an excuse not to do anything with them. The children are 4 and 16 months now - you can at least play with the four year old.
Do not expect me to pay $400 for a week's groceries cos you decided to buy up the whole shop (including things we already have but you couldn't be bothered to check for first)
Do not follow my poor, beleaguered DH around the house asking him to do things for you (mend my computer, buy this thing, fix this thing) when he has just got in the door and would like to see his wife and kids first. And maybe sit down for 5 minutes.
And many, many more..... Sigh. We are currently three days into 2 and a half months of three different sets of visitors...... Oh God, why???
