I get to travel a lot because of my job. It is almost always a lot of fun (except for the working part), and I have absolutely fallen in love with Baltimore. I am almost always by myself on these trips; even when they send someone to work with me, I always eat alone. It used to bother me to walk into a restaurant and watch the hostess crane her neck to see if there is someone else behind me or if I seriously just walked into her restaurant alone. To eat by myself. Alone. Now I just shrug and say, "it's just me..." or "Table for one please..."
I actually like eating alone now; I get a big kick out of watching other people in the restaurant. The big groups are my favorite. The conversation is usually driven by one or two Me-Monsters, with the people on the ends of the table are almost as alone as I am.
Since my wife started PA school, she's been staying with the in-laws while she works with a family practice doctor in her home town. She'll be gone all summer, meaning my solitary dining situation has followed me home. Eating by yourself at home is not nearly as interesting, because watching the entertaining family includes commercials and a laugh track.
