I have also been late for a flight. And often very nearly late despite giving myself huge margins. Some people, like me, just have minds that have too much going on to keep track of. There is no dead space to organise things, its always moving, analysing roving. It just will not stfu. And so there is no breathing space to consider what is going on in the outside world. It's like trying to drive a car while eating pizza. You cant not eat pizza because its the most delicious thing in the world (thinking about stuff) but you must also drive (operate in the real world). Its bloody difficult being absent minded and we dont need you guys who have an easier time of things making us feel bad. Now your probably thinking, well I manage it, everyone else manages it. You are just lazy or self absorbed or both. No. Brains are different. I have a different brain that finds some things very difficult.
