"Good morning"
Ordinary words we say every day, but they don't always mean the same. For you, it will never simply mean "good morning".
It means that I woke up and you were the first thing to come up in my mind, that my first smile of the day came from thinking of you, that I long to see you again, love you again, feel you again... that you are the reason why, yes, this will be a good day.
These are the words I will say to you upon waking because when I sleep I will always eagerly await the arrival of a new day by your side.
