building and reconstruction of slum

I think the experience of building and reconstruction of slum was the most interesting in terms of working in a group of people.
Together we can reach much more then alone.
We are living in society and we are dependent on others.
To start doing something together is the most difficult but process is teaching us tolerance and confronting with other opinions.
That, I think will be especiall useful in India where we are going to be in totally different sourrounding to which we are used to.
