There are a lot of things in this life that a good Getting Things Done (GTD) or reminder app will help with when attempting to sustain (or create) a sense or order in one's life.
Order is important.
Quite why I used the Amazon Prime Now delivery service - instead of going to the shop - to order the following escapes me. Necessary, yet…
In order of ordering:
A 1kg box of shortbread biscuits,
A box of Thorntons chocolates (445g or thereabouts),
A squeezy bottle of tomato ketchup (unfortunately Heinz, it's all they have).
