Have a Hug! There are all kinds of hugs. Porcupine hugs are done very carefully. Knee hugs are good for hugging someone tall. And piggyback hugs are the best way to see a parade. From birthday hugs to Great-Aunt Mary hugs, every hug has a purpose---even a lamppost hug. You should never hug tomorrow when you can hug today. But which hug will you choose?
