a letter of advice
Your brother has an obsession with football. It isn't normal that he watches three or four matches a day or that he goes every weekend to watch matches, this is very expensive. If I were you, I would say to him that he has to choose only one match a day to watch on TV and at the weekend then you could plan to do something together. With the money you would save from not buying the tickets, you could travel. In all likelihood, he would enjoy doing these things with you. Don't worry because he is older than you. If you were him, would you like to have help from your family?
Well done, not bad at all!
