Respect the can’t (Ischemgeek blog).
“People with disabilities and chronic illnesses will often say we “can’t” do something when technically, we can, but not without severe consequences we’re not willing to pay. Doing this is not dishonest. I can’t do the thing, in the sense that abled people are thinking of. I can’t just pound it out and move on to the next thing. It will take too much out of me. If I do it, my day is basically over, and maybe my next few days or weeks will be wasted in recovery. But, abled people, when they find out what I meant by the “can’t” get outraged at it, and seem to think I’m lying about my abilities. And then my can’t backfires, because they take every can’t as a “shouldn’t.” Because then they start viewing every “can’t” as an obstacle to be bulldozed over. You don’t know what’s going on in their body this week. So respect the can’t.”
