I like hugs personally. I think they're great, and I like that hugging differentiates friendships from acquaintances. When I first saw this hugging moment on the show, I immediately felt awkward with Barry. I might have held my breath to see what he was going to do.
Today, while walking around work, I saw him again, this time from the back. I almost fell forward due to the unreal and freakish resemblance. It was all I could do not to burst into tears. It felt like I was being haunted by my best friend.
