passerby

for me ,passerby is a person who comes to you when you are at the lowest point and left when you start to rely on/like the passerby
of course leaving a big mark in your heart that is bittersweet memories


it is ok!!! to leave as everyone has it own life to move on!!! but at least say or send a goodbye message rather than just goes /vanishes into thin air just like that without inform


 adding some colour to your life = > sweet memories

and left without leaving footprint => bitter memories
