My two best friends (all female) and I kiss each other goodbye all the time (though not on the lips anymore, as we’ve all gotten married to other people.) Although I never actually kissed the most recent-acquired of those friends on the lips, but that’s mostly because she’s so short.

The only people I kiss on the mouth are my spouse and my mother, once, by accident. I am totally ok with single, double, or even triple cheek/air kisses as greeting, I just need to know its coming and they have to go for it slow enough that I can tell which way to turn (see above, with my mother).

Not even Richard Dawson? 
When dealing with other Spaniards: I’m used to kisses on each cheek with about any other woman, as well as with men below 55 or so. When meeting someone in a business situation, it’s either nods, shaking hands or, if the other person goes for kiss-kiss, kiss-kiss. I won’t initiate kiss-kiss in a business situation. With foreigners, whatever is done in their culture.

No. Ick. I don’t even like non-family people in my ‘bubble’.

The concept of kissing platonic friends seems utterly bizarre to me.
Happy birthday!

On the lips!? Ewwwwww. The only person I voluntarily kiss on the mouth is my husband, though I’ll tolerate brief mouth pecks from my mom. I kiss my grandparents and niece on the cheek or top of the head, but never my friends. We hug on a regular basis, but kissing is right out.
Jeez, and I thought it was out of line when I moved to the mountains and people I’d just met insisted on hugging me goodbye.
Wow! Thanks for the responses everybody! It pains me to have to admit that my coworker is right. She had never heard of friends kissing each other goodbye before and thought I was strange for doing so. I thought for sure I’d have about 30% or so of you guys doing the same. Personally, I really like the practice. It allows me to be a little closer to my closest friends and share an affectionate gesture. I think the biggest surprise I’ve had in this thread is how some of you view kissing. Very eye opening. Thanks again for the replies!
Aw, my birthday killed the thread.
I’ve lived all over the country - Don’t take my current domicile as definitive: Mid-Atlantic, South-East, Mid-West, West, West Coast…
1) Roughly how old are you?
I’m in my mid-30s.
2) Do you kiss opposite sex friends good bye on the lips?
I have one current female friend I do this with all the time, and a former friend whom I used to do this with. In both cases, it was the female who initiated this habit as it’s just in their nature, and it happens all the time in front of my wife (whom they also freely kiss on the lips)
I have several female friends whom I kiss on the cheek regularly.
3) Roughly where do you live?
Los Angeles 'burbs.
Please feel free to offer any extra information or stories!
The one current female friend with whom I do this caught me way off guard the first time. It was the first time she and I had ever hung out together (we had a mutual friend who “set us up” because we both wanted to see the same movie), and as we were leaving, I went to hug her, and she kissed me.
Much later, after we’d become solidly good friends (and the ritual was well established), I asked her what prompted her to do that the first time. She just said I seemed like the affectionate type, which is true. She is the most affectionate person I know, and she is that way with EVERYONE.
And it’s 1:30am and I’m tired, so I apologize for rambling.
