Help me with my English here.
My/Your nephew always told me how you suffered a lot when you were child and as you would not want would not to pass that to your son, as you would also like to have had a father who held you strong and was always on your side to give you a pat and a hug and encourage you on your journey through life. And you're right to say that I certainly do not feel like that, nor do I know how you feel the pain you have. I want you to know me you have a friend and a brother to you and you also have a father who is waiting with open arms to keep you on his lap and comfort you. You just have to be like a child and love him very much.
