Importance of the Smile?

so I was talking with this guy, and we started talking about smiles. I've always considered smiles important, and I was so happy when I got my braces off because now I had an awesome smile.

Ive always payed attention to guys' smiles, and I still think they're very important. A smile brightens a face. :]

He said he looks for smiles because they're friendly, and that's what drew him to me on that day of grade nine. Do I really have that look about me?

Guys: is a smile really that important? Why?

Girls: " " How much do you care about it?

thanks, =D
