When you said trauma wasn’t a big deal and we should get used to it, drag thought you were being unreasonably flippant.

Not sure what post you read that in, but it wasn't mine.

But then drag read that you think of a flat tire as a good example of a traumatic event,

Nope, didn't say that either.

That’s not what they said.

They were giving an example about how having enough money or not having enough money meaning something ‘mild’ (flat tire) can either be a minor problem (having enough money that buying a new tire and missing a bit of work while the car gets taken to the shop isn’t a problem) or a major issue causing lots of trauma via a lot of ‘smaller’ problems that stack (having to come up with spare money you don’t have to buy a new tire, missing work so your paycheck is too small to support you, unable to get to your kid in time after school, getting in trouble at work for the time you were gone dealing with the tire issue, etc).
