"Why decieve myself? Isnt it obvious to everyone but me that im dying, and that its only a question of weeks, days... it may happen this moment." We can tell this because hes saying that he can die anytime soon.
People work better without distractions. If you mix people of the opposite sex then one thing will always happen no matter what, relationships will form. Relationships are a good thing but at school, they are extremely distracting people often come in late because they chose to spend passing period with their partner, ditch classes, and sometimes even ditch school itself for a day with them. Not to mention if they are in the same classroom they will constantly be focusing on one another. So if this was eliminated people would be able to focus more on their schoolwork and won't have a huge distraction during school, this would leave relationships for off campus.
Hope this helped. Have a great day!
He was very confident that he was going to win the race. There was a hare and tortoise who argued which among them is the fastest runner. So they decided to have a race to prove which one of them is the faster. The hare run as fast as he could. When he realized that he was far ahead of the tortoise he decided to take a nap.
