My weekend is very simple, in the morning, I spend about 1-2 hours studying, playing with my brother in the afternoon, spending time with friends by going out with them, or going to work. garden, help parents. I really enjoy weekend activities because they make me feel good and help me relax. For me, a weekend is very long because they are long enough for me to regain my spirit after a week of studying and working hard. Of course, a weekend will certainly be welcomed by many like me, but I don't see that happening in the near future. So basically, whether or not our weekend is long enough depends on how we plan to spend our time.
