It was just a past

Q.er: What do you think about the past?
Me: It has nothing to do with the present but still I feel sth wrong with it.
Q.er: Is it important to think of it over and over again?
Me: Not at all.
Q.er: So why still you think about it?
Me: I don't know, it's the feeling itself, not me lolz...

Q.er: Hmm... we cant take back what had already happened so why not just being happy with what we did?
Me: I don't know, it's a kinda mixed feeling.
Q.er: Mixed feeling again?
Me: Er... yeah, I always have this kind of feeling.
Q.er: When are you going to get over it?
Me: er...ai...i....i don't know, can you please stop asking me?
Q.er: !!!
