Dear кто то (имя),
I have a nice idea to become a volunteer. Would you like to join me?All of a suden i realised that i need to do somethig for people in need. I want to organise a group of young people who will help the poor. families with many children of different ages. We will ask people to give their clothes and toys for these families.It will be a kind of humanitarian aid. Of course we will not earn any money but I think it is good for us. for our hearts and souls. Please write if you agree to join my group.
