Summarize the following:
When it comes to break ups, face-to-face interaction is optimal but there are a variety of reasons why writing a letter might be the best option.  If you're in a long distance relationship, communication can sometimes be difficult even over a phone or web cam screen. Some people are also simply uncomfortable with phone calls and if that's the case for you, a letter might help you get your words out in a calm, straightforward fashion.  If your partner might become hostile or emotional during a face-to-face break up, preventing you from explaining your point of view, a letter might also be a better option. Closure and open communication is important for a clean, healthy breakup and if you don't think your partner will allow this face-to-face, it may be better to write your thoughts out in a letter. A breakup letter should only be used as a last resort. Unless you're experiencing one of the extenuating circumstances from above, it's better to try and communicate face-to-face.  Face-to-face communication is ideal because non-verbal cues can provide comfort during a breakup. A smile or hug, for example, can tell your partner he or she still matters even though the relationship is ending. Such moments are absent when breaking up happens in letter form.  A breakup letter can also be somewhat cryptic. If there's anything your partner does not understand, he or she will be unable to ask for clarification. A lack of closure can leave him or her emotionally scarred and entering a new relationship may be difficult.  If you truly feel a breakup letter is the best route despite its drawbacks, leave room open for communication. Tell your partner he or she can call you or see you in a few days or weeks to talk if he or she needs to do so face-to-face. Give him or her time to cool down, however, so you can both talk calmly as adults. Delivery options are important in regard to a break-up letter. You want to make sure you deliver the letter in a way that does not come off as cruel or spiteful.  E-mail, Facebook, and other electronic means of delivering the letter are probably a bad idea. As some many people now have smart phones, that means all day internet access. You do not want your partner to open the e-mail on his way to work, school, or any event where he needs to stay focused. Mailing the letter may be necessary if you're in a long distance relationship. However, give some kind of heads up. Do not pretend things are normal after you've sent the letter. Give your partner a heads-up to expect a letter and tell him or her you've expressed some things you feel are easier to discuss in a written format. If you live in the same town, you could deliver the letter yourself or have a friend or family member do so.

Summary:
Figure out if a letter is the best means for breaking up. Consider other options. Decide how to deliver the letter.
