I’m terrible with the name thing as well. I’ve gone so far as to telling the person I’m with ( who I know) and have to introduce to a person I’ve recently met:
“Oh Hi, listen I’m dying to go to the washroom/get a drink/gotta talk to someone real quick before they head out the door/or whatever pops into my mind , why don’t you introduce yourselves,” then dash off.
I actually started a note file on my iphone for names I have to remember but probably won’t.
As for going off topic, yes I can do that but worse is the zoning out when someone is talking , especially on the phone, usually a new thought triggered by what they said.
Try to catch myself and I’m getting much better.
On the other hand, in contrast, it drives me completely crazy when people get side-tracked in a meeting. I am a co-chair for a large volunteer organization and my partner is an expert at that sort of thing. Meetings go on at least an hour longer as a result. Then of course when it’s all over or before the new one starts they all complain because it takes so long. When I tell them I am only allowing 2-3 minutes per topic they get mad at me. I once set a timer and they nearly lynched me after a while. AAAAGGGHHHH .
And Sugar, “Secretarial Slaves” – Seriously 
? Is this what you meant: A very close friend of mine who is a high energy ADHD person plays that card all the time. She uses self deprecating comments to make one think she’s a flake and absolutely needs your help. I finally caught on because I would spend all sorts of time helping her with computer issues related to her job. One night she called me in a panic at like 10 PM because she needed a powerpoint presentation for her work early the next morning (she was getting paid not me!!!) and nearly had me doing it before I caught myself.
I stopped helping her and just told her where to find a good tutorial online. Not sure if she conned someone else or actually did it herself, but I often felt really used by her afterwards. Although she is a very generous person and a good friend who would always be there if needed, there’s a fine line between asking for help to learn how to do something and conning someone else into doing your work.
Now how’s that for going off topic !!
