I don't know what is the problem of this period.
It seems as if we have developed that level of detachment where we can receive a message with it and just forget to reply to those messages.
Maybe we will remember it three days later and still feel like no time has passed. Or we just see a message and we just reply mentally without even actually typing the words or never actually replying to it.
You know they have already responded but the main person that sent the message hasn't got the response needed so they will not ask ourselves is it really the right thing to do or what is happening most of the time we forget to post in our status.
We just we just viewed status of others and us and just pass by so life has become tougher and you don't have time for too much drama and other things.
