I think people believe they can "write you out," but the truth is once you have been a part of someone's life, once you have touch another's heart in some way, you can never really be erased from the page. Yes, you may never see or touch that person again in the physical sense, but the mind will bring forth the times you shared. At least, I like to think so.
I was recently "written out" in the physical sense, but I have a feeling he still remembers the times we shared and the words we said. In a small and odd way, this feeling brings me comfort.
