I always thought this to be an interesting word, and a contradictory one at that.
You say, it’s a bittersweet memory, when you think of someone who is no longer with you. Of somebody you miss.
You somehow feel both happy and sad at having to see that person in your mind’s eye, because you may never see them again. You feel both joy and pain.
I have a lot of those kinds of memories.
