When someone says good morning, it is a form of greeting that I like. In this busy world we live in, people are so busy and rushed with life and it's just nice to hear a friendly voice saying good morning. It makes you feel good about yourself, like you have purpose and your day means something.
It's some kind of a blessing to one another to start the day,

On this occasion, considering that it is the first day we know each other, I also say "Good morning" friends!
