I have a friend who starts every morning I see them with this greeting. It is done out of pure friendly love and it feels so wonderful. Thank You, buddy.
This makes me think? If these few simple words work those kind of wonders on me, what would they do for my son? I try to say nice things, just becuase, to him, but this is a nice reminder. I doubt much of what I say to him still doesn't make a whole lot of sense but intonation and body language is universal.
Try it out on your frineds and loved ones, you'll be rewarded.
