I frankly dont care if you barbeque, go to the park, go shopping, go see a movie, get your nails done, or whatever else you want to do. If you are inclined to remember and memorialize someone that you knew or even complete strangers, then you should do that. You shouldnt feel compelled to do anything.
Of course...all of this not withstanding, you DO understand it was still stupid of the democrat party rep to post a pic of Obama eating an Ice Cream under the heading "Happy Memorial Day!"...right?
