The indefinite pronoun is somebody.
Yes, I myself have bad attitude and I know several of my friends that have bad attitude. It was like getting stung by a bee I did not like the way they were treating me and I was talking so calmly to them and they were still being mean even though I didn't even do anything to them to hurt them. Everyday I would say hi to them and they would disregard it :(
Well from that point on I just stopped hanging around them because hanging around mean people just isn't worth my time anymore to be frank.
I hope this answers all of your questions!
can you please explain your question a little more into detail
I would say that it depends on the student. Some kids need a physical classroom because they can get distracted easily, while others have enough responsibility to do their work in an online classroom. This is just my opinion, but I hope it helps!
