In Windows, this is a pretty common issue. I've run afoul of it myself a number of times, either by forgetting or just not knowing. Truly, though, it's this easy:
open notepad as an administrator *on Windows 10, it's (winkey)+ type notepad*
-- or find Notepad and then right click and "open as administrator"
This is plainly a simple communication fault. It can become a habit from experience.
"Whoops, I broke something of yours, but I forgot to tell you."
"I made a decision that involves you, but I forgot to tell you."
"I incurred this fee/debt, but I forgot to tell you."
If something happens that affects someone else, it's your obligation to let them know as soon as possible. They may not like it, though. The importance of the event is a matter of perception and theirs is most likely different from yours.
The trick isn't so much as to how to word it, it's how to time it.
So when they do find out, though, you shouldn't be so surprised at the result.
This is part of my 're-framing'.
Become a Friendlier Person
I'm going to spend the rest of this summer finishing off all of the projects I've promised to finish, paid/free or trade. I'm not going to take on anything new until I've completed those and constructed a complete web presence for myself as a freelancer.
This is my personal journal. I'm a designer developer on a mid-life journey of discovery.
You will find me on Facebook often, and, once-in-a-blue-moon on Twitter. My grammar isn't perfect, my English comprehension is decent, and I don't really do anything that strikes me as world changing --at least in my mind anyway. You might find a nugget or two of interesting takeaways in my ramblings.
The opinions I put on here are my own and do not necessarily reflect those of my employer or associates.
