Me, my brother and Dad used to go out on the beer all the time and it was great as we shared the same stupid, filthy sense of humour. I owe my taste for real ale to him - he used to berate me endlessly about drinking "that gassy crap" when I went through my lager-drinking phase. Sadly, he passed away three years ago, so those days are gone.
I have a new drinking buddy now though - my father in law. I seem to end up in a pub with him most weekends, especially during the summer months ...
