For me, it's a tie between having no object permanence and waiting mode. My lack of object permanence really shows in my kitchen, because I will keep everything I commonly use on the counter. If Idon't, I forget I have it. Waiting mode really speaks for itself. If I have an appointment, I can't do anything else til I'm done with it. I'm also compulsively early to every appointment because of how angry my parents would get if we were even a minute late to anything.
