People with ADHD often are terrible at reading time in general. Whether it’s calculating how long it would take to do a task, to actually even understanding the passage of time without a tool like a watch or a clock to measure it.
We can be on the verge of being late for an appointment or work, and yet we think in five minutes we can read forty minutes worth of information or T.V.
I won’t say much about this post, but ADHD people being late often or too early is a result not even just of inattention, but a complete lack of time comprehension.
