Determine if there is any unrequited love between you and the friend you want to kiss goodbye. While kisses can convey the depth of the feelings you have for a certain person, they can also trigger feelings of love and desire. Kisses can create a romantic-type situation between you and a friend where none previously existed, so exercise some discretion in who you kiss.Kiss
Bear in mind that platonic kisses may have an adverse reaction on some romantically disaffected friends. While this seems to be more common in males, many females would also rather be kissed romantically than as a friend. Again, this must be determined individually.
Consider cultural and societal norms before you kiss the person. While this may sound overly complex, in reality it is simply asking yourself the question, "Am I going to feel weird kissing this person, and are other people going to think it is weird?"
Decide whether or not to violate the societal and cultural norms. This is especially important if you happen to be from another society or culture, where kissing a friend goodbye is more acceptable than in the current culture. Remember that while societal and cultural norms are important, personal feelings and the bonds of friendship take priority.
Summon your courage. Kissing a friend goodbye requires a display of how much you prize that person's friendship, and it can easily be seen by other people. This is an especially important step for shy people, or people who have not had much practice in expressing their emotions to another.
Approach your friend when the time comes to say goodbye. If you are still shy about kissing your friend goodbye, ask to speak with her privately to reduce the number of people who see you.
Kiss your friend goodbye. Tell him how much his friendship meant to you, in order to avoid any confusion about why you kissed him.
Hug your friend if the situation warrants it. In many situations, a kiss is often followed by a close hug.
Clarify that the kiss was strictly platonic, if you feel it needs to be stated. However, overstating that there is nothing romantic about the kiss may lead to hurt feelings on the part of your friend, so be conscious of what you say and how you say it.
Relax. You have successfully expressed to your friend how much you treasure his friendship, and you can rest secure in the knowledge your friend knows it, too.
