📖 Reading Passage
~1 min readThings I Don't Do
I don't drink coffee in the evening because it keeps me awake. I also don't eat fast food very often; I prefer home-cooked meals. My doctor says these are good habits.
My brother doesn't like sports at all, which is very different from me. He doesn't go to the gym, and he doesn't watch football matches on weekends like most of our friends.
We didn't agree on a movie last night, so we didn't watch anything together. Instead, we played a board game. We don't always need a screen to have fun.
Akşamları kahve içmem çünkü beni uyanık tutuyor. Ayrıca çok sık fast food yemem; ev yapımı yemekleri tercih ederim. Doktorum bunların iyi alışkanlıklar olduğunu söylüyor.
Kardeşim sporu hiç sevmez, bu benden çok farklı. Spor salonuna gitmez ve çoğu arkadaşımız gibi hafta sonları futbol maçları izlemez.
Dün gece bir film konusunda anlaşamadık, bu yüzden birlikte hiçbir şey izlemedik. Bunun yerine bir kutu oyunu oynadık. Eğlenmek için her zaman bir ekrana ihtiyacımız yok.
