Aaron Hotchner and Smiling

I keep seeing comments by fans stating that Hotch very rarely smiles and what not. And I was watching this guy react to the show and in one episode Hotch smiles at what Garcia says and he says thats the first time I have seen him smile (where he smiled in the Sean Hotchner ep a bunch) and Im like are you blind? And So far I have seen and noticed Hotch smiling in more than half of the episodes in Season 1. Its driving me insane when he makes comments about it. I have seen him smile in many more seasons quite a fair bit too. I dont know where this comes from. ok Rant over.
