Although forgetting things is not one of my major concerns or issues related to ADD I do, on occasions, worry that I may have forgot to close and/or lock a door or may have left the oven on after cooking something and leaving the house shortly after. And that worry only occur's when I know my girlfriend is out of the house and will return after I leave (we do have different work schedules). She herself is a worrywart and on the occasions where I am in an extreme rush (thats ADD related) there is that very rare occasion that I may forget one or the other, never both. But when it did happen she gets all nervous and never lets me forget it. But the worry is more focused towards her. I think I may forget where I put my keys, wallet, or some other significant item that was important at the time maybe once every 6 months, and usually it's because I was in a rush when I placed the item down and not in a location that is normal. But there is one area where I forget a lot, it's not that significant as it is not something that effects my quality of life or inconveniences someone. I am a gym rat ( great ADD therapy) and I am constantly forgetting how many sets of a certain exercise I did. Depending on the workout routine I'm doing at the time I may do 4 or 5 sets of a certain exercise, and when I get to the last set I all of a sudden forget and ask myself is this the last one or do I have one more to go. It's a short term memory thing, like a name. You meet someone for the first time and 10 minutes later you forgot their name. If I have any worry it's about forgetting a name of someone that I deal with, not on an everyday occurrence, but enough that I feel real embarrassed that I have to ask their name, again.
