Being Creepers

Today David and I went to this "water ice" place called Rita's. I don't get it because all ice is made of water, but I heard it was amazing. It is kind of like a thick slushy, and we got soft serve ice cream with it. Pretty delicious. The Rita's we went to has only been open a week, and didn't have an outdoor seating area, so we ate it sitting on a bench pretty close to another restaurant. This other restaurant did have outdoor seating.

As I was eating my water ice my eyes lazily wandered over to the tables nearby. I suppose I was staring, but I'm a people watcher, so that's just what I do. David was facing away from me looking in the same general direction as me. As I was watching, a waiter came by the tables to deliver some food. He looked over in our direction, glanced down, then pretty quickly looked back up and continued looking for a few seconds. I was in a nice relaxed mood, enjoying the sun and my water ice, so I just kept staring, not really thinking about it. Eventually he broke eye contact and continued delivering the food he was carrying.

Me: I think that waiter just stared at us. But it wasn't just staring, it was like a double-take. He looked away then looked back at us and stared.
...
Me: It was probably because I was hard-core staring at him.
David: Hahah you were? I was too. It was probably because I was like this:

 Neither of us had known that the other was looking at the waiter. And thus it turns out the waiter is not the creepy one, but me and David are.
