He aprendido que:

• I've learned -
  that we don't have to change friends if we understand that friends change.
• I've learned -
  that no matter how good a friend is, they're going to hurt you every once in a while and you must forgive them for that.
• I've learned -
  that true friendship continues to grow, even over the longest distance.
• I've learned -
  that you should always leave loved ones with loving words.
  It may be the last time you see them.
• I've learned -
  that my best friend and I can do anything or nothing and have the best time.
• I've learned -
  that sometimes the people you expect to kick you when you're down,
  will be the ones to help you get back up.
• I've learned -
  that two people can look at the exact same thing and see something totally different.
• I've learned -
  that even when you think you have no more to give, when a friend cries out to you...you will find the strength to help.
• I've learned -
  that the people you care about most in life are taken from you too soon.
