There's no word to describe what you mean to me. There's nothing I can repay for what you've done to me. There's no one that could replace both of you. There's no way to regret being your child. There's no imagination what would I be without you both. I'm so sorry for making you dissappointed, upset , and sad. I'm so sorry that I always spend your money. I'm so sorry that I am mad everytime you don't let me do something I want. I'm so sorry for everything that I can't remember one by one. In the end , I just wanna  say massively thank you and sorry. I have one promise for you, "I'll make you proud someday" :)
