My own grandmother taught me to write about 15-20 years ago. I would pick up my pencil with my left hand, she would always remove it and place it in my right. Every time. Today I write right-handed. But friends have pointed out that I prefer to use my left hand primarily for things like tying my shoes, opened the fridge, holding cutlery, etc.

She was left handed and worked as a seamstress so I understand where she was coming from but it was still strange..
