Small things teach a lot !!!
Memories are nothing. Memories are everything. But memories are something. Is it? If we have memories about something or someone then today it just gives us the overview about that thing. Not the exactness. It doesn't give us the accuracy. On the basis of past memories about something, we judge them in present. This is what we people exactly do. But this is totally wrong. If we meet one stranger and whatever we'll do, it is based on only present situation. This is what we have to do. If I delete means I forget all memories regarding to someone and meet him/her then whatever I do is only depend upon what his/her behaviour is today. I cleared this concept more by watching video. If you have more bad experience about someone then we definitely do some negative. So before doing something, delete your memories. If we act depend upon past memories then it leads to sometimes happiness and sometimes distraction.
