1. Determine why that person was your enemy. Did you do something bad to him/her or a close friend of that person? Prepare yourself to apologize, even if you don't feel like everything was completely your fault.
2. Approach your enemy and tell them that you want to resolve the issues that you two have together. Apologize, and ask to start over. Explain to that person why you don't want to hate. If you can, try and talk out the problems you had in the past.
At least try to become friends. The more your fight or do mean things the worse it gets! Don't lie to a friend saying they were mean. Figure out what you have in common.
3. Give him or her your phone number or email address, and tell them that if they ever need something, or someone to talk to, that they can call you. By doing this, you're letting them know that you no longer want to fight. Do not offer your phone number if you feel they may misuse it. Also, if they give you their number its important that you don't misuse it either as that will surely make them lose their trust in you.
4. Let this person know that you are sincere. This can't be done completely through talking—actions speak louder than words. Smile when you see the person when you see them, and go out of your way to be nice. Tell them nice things they want hear but they should respect you too.
- If you don't feel as though a talk with your enemy is necessary, or you want to be on friendly terms but not necessarily friends, you can start by just smiling and being nice to them when you see them. This will show your enemy that you no longer hold a grudge, and hopefully they will follow your lead.
5. Initiate hang out time. Invite your enemy to debate, chat about things you have in common or even work together on a worthy cause. Adjust to your friendship slowly—remember that this is a new friendship, and thus that you should not treat your ex enemy like your best friend.
6. Trust your guts if they tell you to be cautious. Test the waters before allowing yourself to get too close. However, being cautious doesn't mean acting cold. Rather than telling him or her your deepest darkest secret, tell them something that you don't care if it gets spread around. See if they tell others. If so, maintain a friendly distance until you know you can trust them.
