I don't know what event or misunderstanding happened to make someone your enemy, or just someone you dislike. But enemies are always eager to point out your flaws, something that most friends wouldn't do. It was once said that we keep other people's flaws in a bag in front of us, and our own flaws in a bag behind us; where we can't see them. But because your enemies highlight your flaws, you now know what they are and you can attempt to fix them.
You can also learn much from your enemies, if you can learn to get past your own pride and accept the views of others. They can show your flaws and problems like no other. You can also see their own and know what traits to avoid. But one thing that many tend to think is that just because someone is a enemy, they are automatically "bad". People have their strengths and weaknesses, and you can learn just as much from their strengths as from their weaknesses. Learn to appreciate the good in everyone, including people you would consider an "enemy".
So like they say, the enemy is the greatest teacher, and it's true to the core. And who knows? Maybe one day you will reconcile with whoever this person is. And from a great enemy you could make a even greater friend. It happens. But regardless, there is much to learn from everyone, especially the ones you dislike.
