Detachment is a loving act and quite often a very difficult one. Usually we have to consciously make the decision to let someone else chart their own course and thus define their own life. We mistakenly think that since we are traveling together, we should be able to influence the direction a friend or lover takes, but that’s not the case. Possibly, our opinion will be sought, and in some cases adhered to, but there are no guarantees. We travel side by side because of the lessons we share, and one of the lessons we all have to learn, it seems, is that we cannot control the actions, the opinions, or the decisions anyone else makes.
