It's all about preparation.

What I really like is taking my homemade lavender soap and just horsing it into an omelette early on, it looks a bit like an iceberg out in the ocean. Then, I've already cut the bread into a scale replica of the Titanic, we reenact the sinkage. A while later the spuds are on. A full bag of them, 5kg, heft is important. Best if you've washed and peeled the night before but if not spreading them around the kitchen floor and just having a roll over them peels well. From friction. While they're boiling, start work on the 4 litre bottle of Lucozade that you remember tasted differently and are fairly disappointed but the "electrolytes" or whatever. Anyway, turn off the spuds and begin to mash. Stop mashing, admit your failures in life and apologise to the people you've hurt or left behind. Grab that fiver you might have stolen from a housemate (the sound one though) and run. The Tesco is only 7 minutes away on Google maps. Scan home that cheesecake and pay for it yourself you real adult, great job. Take that blue token and be charitable.

Eat the cheesecake alone at a bus stop. In the snow.

Don't cry, it'll be ok.
