Bubble theory

Many times have I imagined myself disappear like a bubble, and the memories of me residing in everyone who knows me will be erased as well as I vanish. It sounds silly, I know. I wonder whether anyone has ever had the same thought as mine. An ideal death is the kind that there is no pain to the deceased and no pain to the people who are left behind. I think my bubble theory should suffice. One can become vulnerable and strong at the same time for the people they love. This bubble has a longer life, but it is still a bubble. Its disappearance is just a matter of time.
