Oh no - not you too?!
Out a a family of five kids (and as far up, down and across family lines as we could look) I was the only "southpaw". I mostly didn't notice as my brain seemed to naturally do the translation (see someone throw a ball - and me do it other-handed). I got over the "you a strange one, aincha?" a long time ago (Yes, as a matter of fact I'm probably far stranger than you may recognize") occasionally still get ribbed for my "left-handed pool cue" or "left-handed hammer".
As I said, I do shoot either-handed and for a while tried to force myself to shoot right-handed with the Bushmaster (because of the shell ejection) until I realized that I sometimes got his by the shells either way. I do favor the left as my dominant eye urges me that direction.
The only time I flinch is when I am compared to another southpaw - like Øbongo. yecccch!
