Time effect

I am surprise or to put a more suitable term, overwhelm by how the time affects us.

I just finished reading few conversations with my friends and family that took place one and two years ago.

I realized that I was much closer to some friends than I am now. Without knowing how situations change naturally time by time, many events took place and each and every relationship changes. 

It is something acknowledge by everyone that time flies but not the memories. For me, I don't remember the memories quite well. So when I looked back the chit chat, I don't remember why or how on earth I respond or initiate the conversations. Haha. Past is past.
