The friend who asks whether or not you have the mental space to engage in her vent session is a true friend. That willingness to respect boundaries and not DEMAND that you dedicate emotional energy that may not be available at that particular moment...that's a dope friendship and it should be honored.
But it's not just about boundaries. A friendship that allows you to go your own way and pick up where you last left off regardless of how long it's been since you last connected? A friendship that can survive hiatuses, silences, and space.
These are the connections that rarely ever die. This type of friendship should be protected and honored. Honor it, Sis.
