Everyone has opinions. And the thing is, people believe that these opinions are based on facts, but they never are. For example: a friend and I were discussing age of people in couples. I am 27. But I have what most people think is a very large window of acceptable ages. I would date a 22 year old, if he was martyrs enough for me. I would date a 35 year old if he treated me like an equal. That is what it is: the relationship is based on being equals.
Now, the person I was having this discussion with felt that my age range was too large. I expect she would only accept if I dated ages 25-30. Now why does that matter to her? Because she bas an opinion. That's all it is... what she wants for me. Perhaps she speaks from concern that I will be hurt by people, crushed from the differences. My response was silence, until she persisted. Then I realized that I had nothing but opinions also. Except my opinions are within my own body.
