4 weeks ago, my grandpa died by some unknown disease. It was contagious. We can't save him but we didn't find a cure yet. We are scared by this deadly disease. It was spend by a mosquito and it bit my grandpa. I was angry because a mosquito bit my grandpa and it was carrying a deadly disease. My grandpa was born in Venezuela and was raised there until he was 13. He moved to U.S.A and he started to hate here. But he met my grandma. They became friends until they're 17. They started dating. Then, they got married and had a baby. They never stopped loving each other. But my grandma was sad when she heard the news. Me and my mom come to her house to calm her down. I missed my grandpa. I told my grandma what happened to him and she said "I know sweetie" "how do you know?" and she said this "this man wanted to kill him for a very long time because he had a crush on me since I was 13 but I didn't like him back. he brought some bat's blood and he put the blood in grandpa's arm. and bat's blood has some type of disease." and I was furious that some guy killed grandpa. Over the years, I became a scientist and still finding a cure for the disease.
