Today is my oldest sister's birthday. I'm sending out an internet hug to her since I can't be with her. [2010 update: for the first birthday since...maybe 9 years I will be with her today!]
Maybe you don't have a sister celebrating a birthday today, but why wait? Make your goal today to find your sister and give her a big old hug. Tell her what she means to you. (Lie if necessary.)
Oh, and if you don't have an actual sister? Find a black woman and hug her.
