Let's just all have a nice cup of tea and forget about it.
I think it's fair to say that most women don't always tell their partners everything. I'm sure I am not alone in taking 30 - 50% off of the price of fundamentally everything that I buy, and then can't explain why I have no money left. See the Tesco-no-money-to-pay-scrabbling-around-on-floor-behind-till-for-pennies blog entry.
Sometimes it just makes life easier. There's no moaning, no shouting, no harking back at the past for misdemeanors thought long forgotten. Sometimes it's better to just not say anything at all and everyone's happy.
Could you imagine what someone might say if they knew that you had been out at the shops in the morning, and then maybe later, say 6-ish hours later, your neighbour came to your door to tell you that you had left your car with the rear passenger door wide open and the whole thing unlocked, and a whole bunch of stealable things inside??
I imagine that their first comment is not going to be "Wow! We must really live in a great neighbourhood that nobody has touched a thing.". So I think we should maybe just keep this between ourselves, ok?
