They like to spend the first few days of the holiday just hanging around the house, getting up late and lounging about in their pyjamas.

They have protested in previous years when we have booked to go straight off on holiday – so this year, I have delayed our departure for a week so they can have a few lazy days at home first.

Not that I will be chilling out with them – there are 101 things to think about before we head for the sun.

This year's holiday has added complications as our eldest is staying behind.

So I have a long list of things to buy for us – sun tan lotion, first aid kit, new sandals and swimwear for the boys, holiday reading and a packet of English tea bags for the husband and me – and an even longer list of provisions for our 'home-alone' boy.

I've compiled a 'home-alone pack' for him with lots of essential instructions, beginning with: "Absolutely NO parties allowed!".

I've also included where to find the master switch if the lights blow, how to operate the washing machine and tumble dryer, what kind of rubbish to put in the wheelie bins, and most importantly that he must get up before lunchtime each day as the cat and dog will need feeding and letting out.

I've even detailed how to clean the cat's litter tray, as teenagers seem to need everything spelling out.

The most frequently trumpeted excuse in our house when the boys are asked to help with household chores is "But I don't know how!", so I'm making sure he does.

It's not just shopping lists that are occupying my thoughts. The packing list is pretty extensive too, especially as I'm not the type to just fling a few things in a small bag and go.

I like to be prepared and, as the husband will work up to the last minute, it's down to me to sort out foreign currency, flight tickets, car hire, beach towels, pool shoes, and enough T-shirts and shorts for the duration.

Plus I have the added task this year of moving our few treasured breakables to a safe place, just in case things get out of hand while we are away!
