It's not a statistic, I got the 2/3 from life experiences. If you feel like the majority then you're in the 2/3
My friends girlfriend made a stupid remark once, and only once around us. We were driving through base and we saw some deer. She asked "do people have to lock their dogs up here?" We all looked at her with a puzzled look on our faces. Then she said "don't deer eat dogs?"
After the car got back on the road (I had to pull over I was laughing and teasing her so much) the only conversation was bagging on her. She didn't even talk to any of us for a week after that, we ragged her out so hard.
Seven years later, we still tease her about that one
