Haha! What? I thought people stopped giving each other hickeys when they were like 14 years old, and these two are in their mid-30s. Mathematically practically middle age. And hickeys don't happen by accident. It's not like you accidentally hit your neck on something, you have to actively perform this action.
I will say I did have a girl give me a hickey once, I'm not going to go into detail... let's just say it was extremely painful. I will say that was the last time I got a hickey and I promise I wasn't in my mid-30s that's just how much it hurt I remember it to this day.
