When I see my friends in this situation I totally wave. And not even thinking about it at all I started waving dork-ily. {is that a word?} You know, because he's my 'friend'.... Well when I realized how odd I was being, naturally I become even weirder. So now my wave was not normal... And I'm sure my face looked like a tomato. It was at this point that I realized a few things. First- He has no idea who I am. Second-We are not friends in real life. Third-I love grandpas. Fourth-The light had been green for a few seconds and the mean lady behind me clearly had no idea I was having a moment with Elder Oaks and started honking.
He saw the frantic hand movements and looked directly at me and smiled really big {probably finding me humorous} and waved back. And it wasn't even a 'this is really awkward but I have to wave back because what else am I to do' kind of wave. It was a really sincere smile and wave.
If he ever uses this story in General Conference I'll consider myself famous.
