I regret having such 'phony' friends in high school. I regret that the teachers didn't see these popular phonies for what they were. The head cheerleader was a slut and Miss Senior Class was pregnant before the school year ended. I regret that this STILL bothers me at my age.
This just emphasizes to me how important it is to have good, solid friends. I'm so lucky to have the best friends ever who are always there for me and who I know I can always count on.
