Thank you Miriam, it's clear now!

That's hilarious, people are sensitive. As strong as many people like to pretend to be, nobody wants to be caught in a moment of weakness, or making a typo if they're an instructor. 

Was it pointed out on the discussion forum or in a private message? 

Some people are just not good at taking criticisms. 

I think marriage is unneeded in today's world. Why do we need government and religious approval. 

If you don't get married, it's easier to leave if things sour. 

I feel everyone should have multiple partners for a certain time, then this feeling which you mentioned " When I am with a girl for a while I will be tired of her and I want to have another girlfriend and I don't marry with them...." 

will probably go away. Marriage certainly doesn't enhance love, it's more a government and religious tool in my mind. 

Then again maybe the problem is they asked "boys" and not "men" :)

That's hilarious. I guess neither of you are at fault, but I understand your aversion to smoking.

I once had a skype session with a student where he didn't have his shirt on, it was really awkward and having to tell him to put his shirt on was even more awkward. 

Even stranger than that is the fact that I was put off by the human body, which I myself possess .

Agreed, this is one of the great aspects of social media,

I think the expression power corrupts is wrong though, it just makes the corrupt person more obvious, they were corrupt in the beginning, I doubt a person of integrity could become a politician.
