To say you could have or it could have done, something implies, something was 100% possible. We don't know if the simplest things are even possible if not actually attempted. Maybe there are really 2 choices at a fork in the road or there could be 1 choice or even no choice at the same fork in the road. Perhaps we only thought we thought making a choice. Is this a math problem or a physics problem or do I not know how to use commas and not forget words or forget or getting lost thinking about it or forget the wrong words meaning?
