If somebody will smile to you in the street you will smile too?

I don't think that a person who smiles all the time in public is necessarily a very happy person... they might be :) You can't be sure. However, I do think that people who smile in public are quite pleasant. If I'm walking in my neighborhood and I pass someone and happen to make eye contact, I'll smile back. I have to admit that I don't go out of my way to smile at people though because, in public, I don't like to encourage conversation with strangers if I'm on a deadline or in a place where I'm not especially comfortable. But I think, in general, it's nice to greet another person with a smile... sometimes, it just makes a person feel good to do that :)

Yes, if someone smiled at me in public I would definitely smile back in order to be polite. I feel like that person went out their way to be nice to me so I could at least return the favor. Sometimes, I smile at people briefly if we make eye contact.

If someone smiles at me on the street I would smile back at them. THere have been times when I have had people smile at me driving through the town/city. They smile and I smile back.

of course i would! smiling to another person is always nice whether as a simple gesture or just a response to their smile, specially when you really mean that smile.. a simple smile can sometimes lessen the sadness in another persons heart when the person in front of them smiles, even without reason. it only takes a few face muscles to smile and yet, it does way more than using your whole body to make another person happy..

i try to smile when someone smiles at me .I think it is away of saying hello
