I had celebrated my last birthday in a very unusual way. I wanted to invite my friends for the party and birthday cake, and we were already planning all the details with my mother, but over sudden my small sister got seriously sick, and emergency took her with my mother to the hospital two days before my birthday. I felt myself lost, extremely worried about my sister, and helpless. All of my friends were already invited to the party and I didn’t know what to do. I called my best friend to talk about my problems and cancel the party, but he told me: “Let’s take the cake and go to the hospital!” Why didn’t I think about it myself? I called all my friends and asked them what did they think about the party in the hospital – and they all agreed to this plan. My father arranged the cake in the hospital, and some balloons for decoration, and also he invited a funny clown for all the children. The party was short, but very nice and filled with joy and happiness. We were playing games, laughing and eating my birthday cake, and I was very happy to be with my family, friends, and all the children from the hospital.
