You know what the best feeling in the world is? Knowing that someone cares enough about you to take time out of their busy schedule to send you a simple text wishing you a good morning and hoping that you have good day. I have a friend who does exactly that and I can't even begin to describe how happy those texts make me feel. Because he starts his day extremely early (and I of course start mine relatively late), the first thing I see when I wake up is his text. Nothing better to wake up to than that.
It's just those little gestures in life that make all the difference.
