Once you drift apart from someone you used to be close to, it becomes difficult to reopen communication with them. It feels odd to make small talk with them or call once in a while to stay in touch because you know you would just be playing pretend. When you've shared your most sacred thoughts with a person, it feels unnatural to go back to knowing them in bits and pieces. It just shows you how with some people, there's no in between. You either let them in on everything about your life or shut them out. You either have all of them or none at all.
