We have a cheese box. This is because if you don't cover the cheese up properly once you've opened the packet (looks at DH), then it goes dry and I hates dry cheese. Hence a cheese box.
I had no idea that other people's parents were like mine though. I thought it was just mine that washed up by hand everything before putting it into the dishwasher and turned all the sockets off at the wall over night or when going out - my parents first bought a video recorder so they could record Princess Diana's funeral and then got very upset when it didn't record because my dad had turned everything off before he went to bed the previous night!
Other things are, decanting food from one container into another, even if only a tiny bit has been used. So my mum will serve a bowl of stewed fruit for pudding and then afterwards will put what is left into a new bowl even if no one has had any from it.
The inordinate amount of time it takes to cook things. They get up at 6 and my mum will start the lunch prep around 9. It seems to take forever to prepare the vegetables and put the meat in. She also prepares her veg not on a chopping board, but on pieces of the Radio Times that have been carefully saved for the purpose. All the peelings go into the peely bin, which is fine, but she will not use a bloody chopping board! My dad even bought her one specially, but no, the old pages of the Radio Times are still in use. What is that about?!
The lack of any spontaneity - any trip into town requires a change into jogging bottoms first, plus a toilet trip, then coat, debate on whether it's cold enough for a scarf or not or whether it's going to rain. Then when we finally get outside, it's an lengthy discussion about which route we should take and whether it's best to go via Waterstones first and then M&S or if we go to M&S first, we could then perhaps go to Boots BEFORE Waterstones....
My dad also has pretty much every bill, payslip and official letter they've ever received since they married in 1960. It is all in a cupboard in the sitting room. But none of it is organised. They recently had a major panic because they couldn't find their birth and marriage certificates. He also collects trains, which he buys secretly and then hides in various places around the house in their original boxes, because "they'll be worth something one day", but he never actually gets them out and plays with them or sets them up, which is think is a bit sad. I could go on..!
