I bet everyone went through this phase somewhere in their life before. Suddenly remembering the things and bad decisions you made as a kid, and now as an adult you totally went "why the heck did I do that?" or "things would have been different if I were to...". Especially so for words. Of all the things that can hurt you, in my belief, words are the most infamous of all. Physical pain will go, but mental scar lingers. I always wished that I knew this sooner, so many friendships could have been salvaged.
