The thought of it makes me smile because in spite of the fact that I am not meant for them , and they are not meant for me , there were happy memories . Like this guy from 2002 . We were never lovers ; we were never friends in the first place but there was something different ( at least on my part ) about us . It was a work in progress .

Question: What may be the reason for smiling when remembering people from their past ?
Answer: Because it was a horrible experience .Because they like thinking about their younger selves .Because they wish it never happened .None of the above choices .
