Match diary entry Today I drove all the way down, fifty miles, to Mullingar to watch my son play Gaelic football. He played as a goalkeeper. To be honest to the last moment I wasn't sure if I should go. Our relationship is not the best. I know I wasn't the best father and I'm the one who put him in the mental institution. It's not like I don't love him. I just don't understand him I guess. He is very talented and could do great things. But he wants to waste his time to be a poet. When he is on the field it's only time there is some kind of bond between us. That's only time we understand each other. That's why I dropped everything today and watched him. Journey was long but I felt proud while watching him. Him opponents were very big and seem very strong. But my son fought till end and bit them. I saw he has done his best down there. He did not flinch in the goals. Few of his saves were really spectacular. Diving full streatch to turn goal. He was really focused on the game. Few times he looked at my direction but I couldn't make an eye contact. His team won but for me it was his victory. I wanted to tell him how proud I am but when I've stand in the front of him I thought "Yeah, father of the year. Left his son for tree years and now you think that one match will fix everything? Genius.". So I just shook his hand even when I wanted to hug him. I really want fix out relationship but, it's way too late for that. But maybe if I would start to visit him. Maybe I could even get him out of there. Maybe he could forgive me for how I fucked up everything and we could start from the beggining. Maybe I could visit him this weekend. I will ring the hospital straight away. I have wasted enough time without my child.

Letter to a teacher Dear Mr. Wonka, I am disappointed with decision of allowing fidget spinners in the classroom maded today. I am worried that those are just an objects of distraction for students in our group. Today boys in the front row instead of doing questions were playing with their fidget spinners. Fidget spinners are not distraction only for students who own them but for everyone around because of the noise which accomponate playing with it. Fidget spinners do not let students focus on the task. I think that they should be banned. I look forward to a response to my letter. Thank you in advance, for taking time to respond to my complain. Your sincerely Alice.
