Hugs

Hugs are like emotional food. They give a starving person something to go on for awhile, or give a content person the comfort and security of knowing that all is well.
I didn't discover how nice hugs could be until I moved into a dorm where I was surrounded by nice girls who gave hugs on sight. They didn't just say "hello," they also said "it's good to see you" with a hug, which made the greeting more complete and genuine. I used to be a bit stand-offish, or touchy, when it came to hugs, because I was easily embarassed and not sure how to react. However, the hugs-on-sight girls helped cure me of that, and I have since become more of a "huggy" person. Some things you can say with words, but a hug often does it better: "I've missed you," "until we meet again," "I appreciate you," "sad to see you go," "I treasure your friendship," and so on.
I've learned from past experience that if you never show the affection or goodwill you feel for someone, that person may pass away or simply pass out of your life and you will have lost the chance, it will be too late to hug them and communicate "I am thankful for you...you are always welcome here."
So, to all my friends and family, think of this as a virtual hug for you until I can give it in person; I am thankful for you!
