Everyday, I walk past the security guard on the way into my building. And in my last building, he sat behind a desk that was only in view when you walked through the door. But the guard at my new building stands in the middle of the foyer, so you see him while you walk from the garage to the doors. So I have to avoid eye contact until just the right moment, so I don't have to nod at him twice. And I keep screwing it up because I forget every morning.
So this morning, I looked up when I came around the corner and he was looking out towards me. So I gave him the customary nod and then lowered my head so I wouldn't have to look at him again. Then I forgot after about 10 steps and looked up again. And I made eye contact by mistake again so I gave him a second nod out of habit. So I dropped my gaze again and walked through the door. Then I had to give him my normal verbal greeting ("Whaaaaassssssuuuuuuuuup?!?!") and I accidentally nodded again! He probably thought I had some kind of nervous tic.
If I could pull off wearing sunglasses, I'd do that. That way he'd never know if I was looking at him. Unfortunately, I have tiny little eyes. So when I wear sunglasses, I look like a nervous tick (Get it? Look at the picture!).
