Door to my heart...

An incident this afternoon made me realise that no matter how much time have passed, the people who once mattered to me still do. Maybe to them, I am but a stranger along their path but somehow they still manage to pull the strings of my heart. I suppose once I've invited someone into my heart, it is hard for me to let them go. People say time does make a person forget but how true is that saying? Maybe I am being selfish. Maybe I am being a coward. To better protect myself, I will just have to add more locks to the door leading to my heart...
