I know a few blokes who say they never ever open a bottle without company...why I ask? They have no answer to that question, just don't like drinking alone is the usual response.
So why is enjoying a glass of wine or two in your own company a problem for some? Do they enjoy a cup of coffee or tea alone...'cause that is drinking too isn't it?

I personally find a glass of wine or two one of life's great pleasures to relax with after a long day at the office...
