From literally instant acceptance of a stranger under most conditions to the Hoytt Dobe who simply tolerates at best the presence of someone not known to it either as a family member or friend and you have some idea as to the low and high suspicion level. For most the mid-range is the best choice since it allows for eventual socialization with the same stranger it first did not trust. This as in all other areas where you may have a question should be discussed with us personally.
