TIL. I've never heard parking lot style parking called "stall parking" before (or anything for that matter), but that makes perfect sense!

Hmm, I mean, I would never lean that way. I can't realistically have negative income next year. That's just not a thing. You can have losses if you look at it that way. I don't think that's really the spirit of the question at all.

As for what you found about businesses, I mean, you're not a business. It's a vastly different context.

It's a weird one. That said, there must be "an answer" somewhere. You're not the only person living off of investments afterall.

I would go with B.

This is why, and I think this is as reasonable of a reference point as it gets outside of some clear cut definitions from creditors. Consider if these were retirement accounts and how income is reported.

If the money was coming out of 401k/IRA/etc. accounts, you'd say your income that year was 50k. So I'd report what you get out of it on average.

That said, I have no idea how they would want you to properly account for it. Although, I feel really confident that it is not option A.

>the parking is parallel so I don’t know how I could have hit their car without realising, especially their front bumper.

Parallel parking is when you are parallel to the curb/street, not to the other cars. I.e., one car in front of the other and you may have to park between the rear bumper of one car and the front bumper of another. So you could definitely hit somebody's front bumper parallel parking (with your rear bumper most likely).

Perhaps you mean the cars were parallel to each other? As in you pull into spaces that are side by side.

But if you didn't hit them, I'd ignore it.
