Do not leave your handbreak off and let your car knock down the neighbour's wall. (Although that one was quite funny, for me and dc)
When your hostess gets an urgent phonecall to go and help a friend in the village with an urgent childcare/illness problem, do not attempt to go along to 'help'. This is an elaborate reciprocal arrangement that we use to get some time out from our mothers when they visit us.
Do not preface every single statement with, 'sorry'. The dc and I count how many times you do it.
Do not criticise that my neighbours have lovely gardens and therefore they must have 'nothing better to do'. If you really must satisfy your urge to criticise, read the Daily Mail.
Do not criticise me for buying the Daily Mail. I only ever buy it when you visit so that you can find something to criticise that does not involve me, dc or my friends.
Do not criticise dh for not being around to help with dc. He only plays golf when you visit, for obvious reasons.
If you are going to park yourself in my house for days on end, please bring my father, so that at least he can take you out for the odd walk to give us a break. Although he probably sees your visits to me as his 'break', so I guess we have to share the burden.
Do not expect me to fall back in horror when you tell me which sons of your friends are homosexual. I don't find it horrifying, I don't want to talk about which ones played with my dolls. Please refer to my previous comment about reading the Daily Mail which I have helpfully bought for you.
Please do not criticise me for being 'too thin'. I think that your only regret that I am a healthy weight is that you can not tell me that I am 'broad in the beam', which you said to me when I was 16 and you are bloody lucky that I did not develop an eating disorder.
and please, please do not then describe your visit as 'helping Jemima out'.
