I feel quarantine is a period for people to stay at home and explore our own interests. But the schools are still taking classes, which leaves us no time to explore our interests. By taking online classes, I personally feel like missing my friends and my conscious is telling me to go their houses, which will break the basic rule of quarantine.So the conclusion is that online classes are harmful to us. I bet, many people want to use this quarantine to keep some time to themselves. Online classes are making me mad.
