Wondering........

Just a casual question....when someone says...praying, I will pray for you, you are in my prayers, what does that mean to them?  Are they earnest in their prays for you?  Do they just say it... then hurry on to their next life step, or to the next problem of someone and say the same thing.  I really wonder how many people, actually stop what they are doing and send up a prayer...that very minute.  Or how many remember later on in their day or night.  Just a casual question......
