> a force that opposes the relative motion or attempted motion of two solid surfaces Or, more commonly, a *thing* that hinders individual progress. I think about [[friction]] and [[systems]] a lot in daily life. Any type of [[relationship]] is a [[system]] and is susceptible to [[friction]]. When i use the word [[relationship]], most/many will jump right to interpersonal relationships. Wife/Husband, Boyfriend/Girlfriend, etc. While these are indeed types of relationships, I generally am thinking bigger or deeper. Employer/employee, job or role / description.
