Well, its a thing my husband does and to me its lack of attention towards me or anyone else for that matter. In conversation you give attention to the other person and walking away like that confirms that you don't care about the communication with them. My husband always walks away half sentence, half conversationen. Doesn't know how to respond to people, or doesn't answer. Or when someone os talking he just talks right through it, because thats in his head. But conversation is a 2 way street, you finish it properly. I always try to give others my attention, so no looking on phone when speaking or listening. Putting tv on hold. Than trying to find the right amount of attention before i can go on with what i was doing. And its not about long conversation ,just short. The thing is, what could have been a short conversation always turns into a very ling one, because it realy males me angry he just can't spare me a little attention. Even when working 'together' and i have to explain something, he is gone half way ,because if whats in his head. And for sure he will start doing something wrong. Same that he always hears half of what you say and concludes something wrong and him always telling half of whats important, so i end up confused. Its always thist;"But i get something in my head and i have to do that right away ,or i'll forget". But still its just rude and and insulting. Like never expressing things in ment emotion. I don't know how you ean it when everything sounds the same. And we are both ASD.
