Well I'm single now, but I met my ex in a bar. I am surprised I am the only one on this thread to have met someone this way so far! We had a lot of mutual friends though. I made a beeline for him and we spent most of the night talking (drunkenly!) That's the English way however; to ask someone out you must be inebriated. A lot of Brits don't have the confidence to ask someone out sober - what if they said no?!! A comedian called Russell Howard does a great bit on this, comparing Americans to Brits.
I don't think I could meet someone online. I have ridiculously high standards and I'd be terrified to meet them in person and realise they aren't the person I thought they were - in looks or personality. Also when I have had guys message me, the majority of them are so horribly sleazy that it's really put me off online dating.
