Hmmm... define stranger. If it's the "Who the hell are you?" stranger, then definatly not. I would look really wierd doing that, and the person I kiss probably wouldn't be so happy about it. xD
However, if it's the "Iv'e seen you around quite a few times before, but we never really talked" kind of stranger... 9.9 times out of ten, it would still be a no. I have this situtation in my head though where I would. Problem is, I'm not to sure what that problem would be. xD
If I knew the person, of course.
Wow, me and my friend were talking about this actually a few days ago where she was like she kissed a stranger. But she knew the person. xD. Just not so well...
