I usually lose any control of myself if I plunge in a conversation with somebody. Some short exchanges are structurally short lived (like with a shopkeeper, or if you ask an information to a passerby in the street). But if the conversation has some consistence and durance I lose completely control and I need often a long time to reconstruct the bubble in which I live (in which I only may live). One technique I employ with some success is to devote myself to solitaries for some time after quitting the exchange. As solitaries (free cell for example) engage the left hemisphere only, I hypothesize that engaging the left hemisphere I may put the right one at work to rebuild my emotional bubble. I may suggest that this is one reason for which people in the autistic spectrum tend to “lecture” others. Lecturing others about some subject you think you know well avoids dialogue and maintains your false “integrity”.
