Which is your favorite part of the human face and why?

Lips/Mouth. Smile lang ng smile. I love laughing and smiling, so I also find it attracting if somebody else has this smile (not necessarily a killer one, but at least something genuine) or laugh that's really worth noticing. I also analyze people thru it, so... there.

Ask anything. Whatever. Make it sensible and I'll make sense for sure. =)
