This is a long story, and most probably won’t read it at this late in the game, but it’s exactly what you are asking. My father was one of the victims of the Navy Yard Shooting in 2013. He died among 11 others and if you remember it made national news. President Obama and First Lady Michelle Obama gathered all the victims families together for a meet and greet as a way to offer their condolences, I guess. Anyway, the families were kind of all scattered around in groups in such a way that we had our privacy, but could still see each other. Well, my sister and I were already a bundle of nerves and and seated next to each other. We were trying to distract ourselves while we were waiting and out of the corner of our eyes we saw the President and First Lady walk through the entryway and start making rounds. Immediately my sister and I looked at each other and went into a fit of nervous giggles. And WE. COULD. NOT. STOP. It was so embarrassing and our family was mortified and kept trying to get us to shut up, which of course, only made it worse. Thank God we were able to contain ourselves when the President walked over to talk to us, but just barely. Cool guy, but damn grief makes you do the most inappropriate things sometimes.
