Have you ever reconnected with a person from your past, only to find they are nothing like the person you remember? Maybe it isn't a memory issue. Maybe life just changed the person into someone totally different. Either way it's extremely disappointing. A let down. A major bummer. You wish you could get a refund on all the time you spent thinking about that person and wondering what became of them.
I had such an experience last summer and I'm still trying to "process" it. Time has not been kind to this person. They have become completely self-absorbed and wave a "I'm Bi-Polar" banner with pride. Hey, congrats on that!
If I could do it over again, I'd leave this skeleton in my closet. I've learned a lesson for the future, regarding the past. I'll be letting sleeping skeletons lie because some questions are best left unanswered.
