In my opinion we do need other people. One just isn’t enough. I don’t think it’s enough for the one and it’s too much responsibility to the other. Of course we don’t have to, our bodies won’t physically die, but I think it makes life better.

I also agree with your T that online isn’t the same. Other people may challenge you, even irritate you, but in the end having them is both healthy and rewarding.

I do find it strange that you think friends would automatically be irritating or lead you to drugs and crime. I’m also a very shy, introverted person and am generally terrified in new social situations, but this is a leap of logic I don’t make.
