I think part of why time blindness / chronic lateness gets such visceral responses is that the behavior is a broken promise generator. The impact feels very personal.
Continuing with the walking stick metaphor...it'd be like if the person with the walking stick was frequently committing to go jogging, hiking, etc with others. They know the activity might be beyond their capabilities, but they keep saying they'll go on the difficult hiking trail or whatever. This impacts the plan for everyone else.
Saying you'll be somewhere at a particular time is a commitment to someone else. If you're making commitments and frequently breaking them, people will react badly to that.
Having had a number of chronically late people pass through my life, I've often heard "be there in a second", "I'm on my way", "5 minutes, max" and similar phrases once the person is late. What I rarely hear is proactive acknowledgement and ownership of the issue.
The commitments you make as a chronically late person need to include your chronic lateness as a factor, just as the mobility limited person should take their limitations into account before signing up for the group hike.
That's a good assessment, but it misses the fact that the person with the effective dysfunction genuinely believes they will 'be there in a second', because they cannot accurately assess time. The lack of forthcoming contrition is not difficult to explain, shame discourages people from drawing attention to their faults. If it's happening frequently, one would always be feeling 'faulty'. Aversion to that is expected.
So you agree with nomdep? If you know you have time blindness it's a good opportunity to do something about it. I tend to choose the be really early option because that works for me. But it can be stressful for sure. And I probably don't get as much done as someone that can organise their time better. That's just the way it goes.
False dichotomy. You can both take measures to address an issue you have, and still know that won't always solve the problem. Being really early sometimes is the only option, but if you're always doing it, regardless of how critical it is, you're wasting a huge amount of waking life.
Everyone wastes a huge amount of waking life on something, whether it's sitting around waiting for an event to start or watching TV or scrolling social media. So what.
So, knowing how much time and effort is required to maintain such responsibilities, you think someone with a similar situation, but who also has trouble being organised in general, has extra time to twiddle their thumbs for half an hour or something, before every single obligation with a time attached, just to be sure they don't get distracted? Do you have any comprehension of how ridiculous that sounds? If you're less capable of completing tasks you need more time than a typical person to do so, not less. They don't give students with ADHD less time in exams to ensure they can break task and put their pens down on time.
Still pushing those preconceptions, eh? Is this how you approach everything you could learn from? Assume you know all the answers before actually studying? Your teacup is full.
