Words?

I want to convey a message of community spirit but have been finding it difficult to decide on what text to use.
I have looked at a few different ideas such as various greetings... This spurted from an idea that when you go for a walk in the country people generally say 'Good Morning' when you walk past another person on a walk, of at least they nod their head. In the city this doesn't happen so I wanted to encourage people to say hello to each other.
However it seems unrealistic, if you said hello to everyone in a city you would never stop talking!
Another idea was to use local stories from local people. On "www.thisisnottingham.co.uk" there is a section where you can send in poems to the site. After looking through them I found 3 poems that had really nice messages behind them. One example is called 'Hero' sent in from 11 year old, James Norton.

A hero is someone brave

He would sail over the highest wave.

A hero is someone who has no fear,

And always turn up with the right gear.

A hero is someone strong,

And he never gets anything wrong.

A hero is someone with a good heart,

Hero qualities are in us all

And he sticks to it from the start.

Hero qualities are in us all,

It doesn't matter how big or small.

All that matters is you go the extra mile,

And you have a great big smile.

JAMES NORTON (aged 11) Clifton

I would like to use this poem and maybe one or two others to make people see their own city in a good light and to make them smile. Smiling can be the start of community spirit.
