Growing up almost deaf

Growing up was very difficult for my grandfather. After Highschool he went to college, where he met my grandmother. After about a year they decided to get married, but then he was called to war. So they postponed the wedding untill after he got back. My grandfather was scared to go because he had just started a whole new life with his new wife. He went to become a navigator. This job was the hardest, and one of the most important jobs. He had to learn how to read all the maps and coordinates. It took him about two and a half months to get it down, compared to the others who took about four months.
He would often think about his wife, and send her letters saying that he was ok and that he missed her. When it was finally his turn to go into the air he first had to get to know the person he was going to be with. This person was known as Jack, who actually turned out to be his best man at his wedding. Everyday Jack would give him coordinates and my grandpa had to find it within 5 minutes, they did this because they didn't know where they would be going. Jack was the pilot who my grandfather would be partnering with. All of this training was taken place in Florida. When they were finally called out my grandfather was really nervous. When he got a notice from his soon to be wife, that she was pregnant. This got my Grandfather really excited and it got rid of all his fear.
When they were in the air, he just kept thinking of what it would be like to have a son or daughter running around their house. Now flying up in the air in a Jet is quite loud, so it was hard for him to hear anything. So he couldnt hear Jack asking for the Coordinates. He got them to the place where they wanted to be, but he could not really remember anything. He remebered swerving, swearing and a whole lot of explosions. He closed his eyes for most of the grewsome stuff.
After this whole expierience and going through this over and over again he started to notice that it was becoming harder for him to hear. At the age of 37 he had to get hearing aids because he could barely hear anything. After the war, he returned to college wearing his new hearing aids. He graduated with a writing degree, he actually worked with his wife Lucille Wong. Now the army is paying 20% for his hearing aids. This is very low because they only recently started to help him financialy with his hearing aids. This is unfortunate, because now he is almost completely deaf and could not hear us talk very well. So we have to go up to him really close and speak loud and slowly.
