It can be shocking, even humorous, when someone knows very little about tech and is literally scared of it.
My sister begs me every few months to enter 3-5 new payments on a spreadsheet and send her the updated sheet.
Now you have to understand how simple this worksheet is. It literally is just a list of payments and payment dates in columns A and B, and a big formula at the top, something like: "="Paid: " & sum(a1:a100) & ", Still left: " & (30000-sum(a1:a100))
That's it! That's the whole worksheet. Yet she feels I am doing her a gigantic favor every time I type in those 3 numbers, hit Enter, and send her the updated sheet.
