I have observed/experienced one strange thing over a period of years in my life and i m pretty much sure that most of the people had observed it too. The first song you hear in the morning leaves its imprint on the brain for the complete day. We keep humming or singing the song for the whole day and at one point of time realise that it just happens and our mind keeps on remembering it and lets us know about it due to which we sing or humm that song. I have come across this situation many a times, i can say almost daily even today.
Does the same happen to all of you?
