Every morning all 3 boys (who are all in their teens) will say "Love you Mom" as they leave to walk to their bus stop for school. Even if they are in a foul mood, not feeling 100%, or if they are rushing out the door because they got a late morning start, every single one of them does it. In fact, there have been times when my oldest was running late and rushed out the door without saying it, but then I'd see him from my desk run down the driveway, pop his head back in the door to yell "love you ma" then slam and run out again LOL It means everything to me.
