Being left-handed (or in the top 10% as I prefer to call it) can lead to one or two 'Are you kidding me?' moments. For example, years ago, I had to listen to some guy next to me at a dinner party offering their theory that all left-handed people were seriously brain-damaged - until the host chipped in and said he was a leftie along with his son.
Another time, again years ago, I had a first date with a woman with whom I got on great with until I signed the bill and she froze completely, looked like she might burst into tears at any moment up and didn't say anything until we got to the taxi rank. When I asked her was there anything wrong, she answered, "Why didn't you tell me about your condition? I think it would be best if we never see each other and you never contact me again!" (P.S. I've Googled her condition and it's called Sinistrophobia) http://common-phobias.com/Sinistro/phobia.htm
We know the stories of older generations who were taught to write with their right hand and beaten if they didn't. I've also been on a cooking course where the guy running it refused to run through basic knife skills with me as I was left-handed and suggested I should only use my right. There are left-handed forums, one entry I read was entitled, "Could I ever love my daughter if she was left-handed?" I sh-t you not!
So, to any lefties out there - what are your experiences, good or bad? (BTW, if you are a South-paw you're in good company as per the below link.
