My typical Saturday
I was drinking till morning yesterday, I got up at 12:00. Then, I did housework such as dishes, laundry, clean my room. After that, I did (some) exercise. Then, I made a dinner. Finally, I started studying English until now. It will be raining tomorrow. I was supposed to go fishing if the weather was good. If I cannot go, I swear that I will study English and programing stuff !
Nice work! English tense is sometimes tricky, as you can use the present to talk about the future.
がんばって!
