"How to be alone"?

I saw this video in a forum:

Somehow they always forget to mention the other side. The awkward waiting at the table in a restaurant until your food is served, when everyone thinks you have been ditched. Or the time until the movie starts when around you people are talking, laughing and having fun with each other and you just stare at the empty screen, hoping the commercials start soon. Or the super cheap menues, that are way too much for one person alone. And they way you walk through strange cities and discover nice little things, but there's no one you point them out to or tell about it. And all the "buy one, get one free" stuff, the vouchers that give you one free entry into a museum when you pay one full entry, the "two for the price of one" drinks, etc.
Being alone isn't all terrible, but it isn't all fun and sunshine either.

I have been alone to the cinema, to the fair, to christmas markets, to concerts, to restaurants, to musicals, to theme parks, to pubs, to festivals, to holidays. I have been alone on New Year's Eve.
And there was always at least one moment when I felt lonely, when I wished for someone else to be there with me.

For the past years I have done pretty much everything alone. With the exception for when I visit my parents I live my life alone. Every day.

Tonight again.
But what choice do I have?
