Friend :(

A guy sat down across the table from me a while back in the library. He took out a book and started to read. He wasn't special in any way, seemed like the most normal guy in the planet. He seemed pretty wrapped up in his book but when he would take a sip of coffee I could see him look at me. Just curious, not suggestive. I snuck glances at him too. I think I fidgeted with my hair too much. Then, he got up and left a minute ago. I watched him go and felt sad. Like a friend was leaving. Funny how strangers can be our companions.
