Do I need to differentiate between the left or right arm if it doesn't matter if it is their left or right arm? Example: If I am prone on the ground and I use both hands to lift myself up and one of my arms gets pulled away or slips, should I worry about saying it was my left or right arm? "Then my arm was pulled out from under me!" "Then my left arm was pulled out from under me!" I think this could be applied to any object or body part. Like Someone poking another person's eye. "Then he poked me in my eye!" "Then he poked me in my right eye!" Is the more specific example necessary when the exact detail is unimportant (or at least appears to be)?
