My shoulder is cold

I have a friend that I typically see once or twice a week. It’s not uncommon for us to go as many as 10 days without seeing each other. This week she’s gone across the country to celebrate the holidays with her family. I’m very happy for her and for them as I’m sure they will all enjoy the time together. But, I miss her. It hasn’t even been a week since I last saw her but knowing she’s not where she normally would be is making me feel slightly off, like a part of me is disconnected, or out of place. You know that feeling when it’s cold at night and you’re all snuggled in a warm bed but your one shoulder is out and that’s cold? That’s how I feel about her not being here, my one shoulder is cold. Have you ever felt that way about a friend?
