It seems like dreamy memories though they were true a long time ago but they are fading away like smoke. Memories are there in our hearts, deep-rooted, and they hurt when you remember them in hard times. There is always a nostalgia for the past; free life with fewer responsibilities, with less sadness, with fewer duties, with fewer realizations, and with fewer deaths!
We remember the minimum details of these memories and they shockingly remain vivid as if they occurred yesterday. Maybe a memory of a friend, family member, ice cream, toy, place, etc. First, they bring a smile on your face. Then, we compare the present and the past to find our tears are shed! Is it because we miss these days? Is it because our present is tough? Is it because we are adults now? Many reasons but no specific answer!
We rarely care about the answer, I think. We just keep these precious memories inside our hearts but we do not realize that today is going to be a memory as well. So, we 've to enjoy as well; making it the best memory as much as we can.
Don't forget the past is a memory and the present will be too! So, enjoy life as much as you can!
