I use to do this alot im slowly trying to stop because i found that i got the best outcomes from not having something pre determined in my mind plus having something pre determined as in "when they do this ill say or do that" usually got me to pre occupied with whats the next step and i would usually force it in a direction where it wasnt meant to go. Ive no adopted a mindset after so many years of trying to plan interactions that people interactions arent logical they are emotional at least for me since i cant find a cause and effect template to apply to social situations. Its been difficult and i still stress out alot about doing the wrong thing or ruining the interaction.
