I went to a very small high school, my graduating class was only 32 people, and in our sophomore year, half of the total class splits to attend the Joint vocational school to learn a trade, and thusly the amount of people that we saw on a daily basis was about 20. Thusly everyone knew each others names, if not their life stories. I think i will know the ones i was closest to in the next 10 years, surly my best friend, who i still see more than once a week, and a few of my other really close friends.
I think i will still know these two in the future, because of how tight we have been since seventh grade, though we have had our ups and downs just like any friendship, we still know each other better than we know ourselves. I feel that this, accompanied by how often we see each other will keep us in touch.
