I'm a lefty as far as writing goes, but for anything else I use my right hand. However I can also use my right hand to write, just that it looks like complete rubbish. Maybe if I had to forge a letter or school report for my 6 year old sister, I'd use my right hand. XD
I like being left handed though. The funny thing is me and my closer brother are both left handed, but my two younger siblings are right handed. My parents are both right handed so I don't exactly know how people get their...handedness?
Does anyone know?
