You can feel a lot in a hug. Some people make it short, casual. There is no squeeze, maybe just a pat on the back. Some people let it linger. Some people rub their hand up and down your back. Some people kiss the cheek or neck--not suggestively.
I was lying here in bed and staring at the ceiling. I thought about when the next I might see Ryan would be. How would that be? I was picturing some type of public place where I was with my friends and he was with his and we noticed each other. I smile a short twitch of the corners of my mouth and do a very subdued hand gesture saying "hi" from a distance and mouthing the words without sound. In his eyes I can see that he doesn't know exactly how to react. I feel somewhat the same inside. I'm happy and sad. Happy for the chance meeting again, sad because it forces memories. We hug, and I don't want to let go.
A hug can be very close.
