Emotional Hangover

My best friend got married yesterday. I couldn't be happier for her. 

At the end of the night, inside a sweltering art gallery, I danced to 80's music with a group of old college friends, some who I hadn't seen in years. For a short time, we stopped catching each other up on our lives and just did what we used to do every week together, dance and sing along with songs. After the bride left we went out to a bar; but we're older now and after one drink we all agreed that it was time to go home. I'm not sure when I'll see some of those people again but suddenly I don't know how to get on without them.
