I was asked to organize a fundraising for children who are fighting cancer on the Belgrade Kids Fair by the organization "Always with children", where I volunteer. They are helping children fighting cancer in Oncology hospital in Belgrade. In my school (Mathematical grammar school) I lead a humanitarian club "Champions of heart" and with a few amazing and supportive students from our club and my other friends, I volunteered to help this organization to raise money and make life of children fighting cancer a little bit brighter. We talked with passersby, handout leaflets, sold hundreds of toys and fridge magnets decorated by the ones who we help and we also asked people to give donation if they can. We wish to make a difference and find a way to help those in need. Our little can mean a lot to somebody, please remember that!
