I sent my dad a text.
A simple little text.
While I was at work.
It read "Just wanted to let you know how much I love you, Dad."
I got one back saying "I love you too, my girl :x" (evidently that is a kiss! Oh the things you learn about technology from your dad! grin)
I'm pretty sure his text back to me warmed my heart as much as mine to him warmed his.
Tell someone you love just how much you do; one thing I have learned in my family (due to a situation I will share over the next few days) is that you really are never guaranteed tomorrow and you may live to regret the last words you ever say to someone.
No matter how upset my family gets with each other, our last words are always, always, ALWAYS "I love you".
