If you meet someone who has knowledge that you don't, do you pepper that person with dozens of questions to get the knowledge you want?
Once the information you want has been harvested from them do you find yourself ignoring that person afterwords since they are fully harvested?
If someone is no longer interesting because they dont any more information you desire, do you ignore them?
As harsh as it sounds, I like to keep my quantity of relationships manageable and keep the quality high so I tend to harvest and bolt.
For example, I have never worked in a factory or on a farm. My ever gregrarious ENFJ wife drags me to some average couples house for dinner. I storm the husband and wife as the opportunity presents itself for some knowledge acquisition of their experiences that I dont have.
In essense I dig around in their mind for any knowledge I dont posess. It usually doesnt take more than one evening, if that, to examine an average couples wiring and database so I NEVER agree to go back because theyve got nothing else Im interested in.
