I don't think that you can really make an argument for either, unless you had some sort of quantitative proof of a deeper relationship. Otherwise, we wouldn't have any way to compare the depth of our relationships. As for your first point, I have a friend that I met in high school, and we hung out almost every single day during and after school. We hung out so much that our families just sort of adopted each other. In any case, he had to move to a different school after sophomore year, but even so, our friendship is still very strong because we still hang out almost every day over the internet. He is my best friend and would trump any of the friends I see from day to day in real life. The friends that I meet day to day still mean a lot to me, but they still rank below my friend that I haven't seen face to face for almost six years.
