I dont know if one MAKES friends, I guess we become friends with whom we like or admire or want to share a friendly relationship with.
How much can one share? Entirely upto the individuals involved. Sometimes you may want to share more, your entire life history with gory details 😛 or you may do selective sharing. It is subjective, in my opinion and there cant be a line drawn at what can be said and what cant be.
Can feelings not be discussed - Why not? But then again, the same answer - would depend on person to person. some may share, some may not. I say, no harm. Feelings are meant to be savoured and lived and not repressed and hidden.
What is being "personal". Something which neither or either party to the friendship is comfortable discussing, that falls into "personal" or "none of your business" category. In some cases, talking of ones affairs in detail may not be personal while to another, discussing the love life of the neighbour may also be personal. The topic is "personal" and individualistic, so the answer would vary from person to person
What about getting told that you are too personal - No big deal. Just a statement to inform you that the person you got "personal" with does not appreciate sharing those thoughts. Nothing personal about it 😛
If someone asks whats wrong, you tell. Obviously, else why did the person ask what is wrong. If it was merely meant as lip service, they should add that clause in there as well, so that they make it clear that it is mere politeness or lip service and the question needed not or should not be answered.
Is it not the job of the mentor to teach what is appropriate? Maybe. But that person can only teach you what he or she thinks is appropriate or inappropriate. Best is to take the advice of the mentor and then apply it yourself by analysing the circumstances without adapting the advice given verbatim
Cant a person be friends with a mentor - Sure. U can be friends with anyone. Friendly mentors are amongst the better mentors, they use friendship to break the student mentor barrier to reach out to the student. By the same method, they retain enough dignity to be able to distance themselves from getting too personally involved.
What is small talk - Whatever is not large talk or part of a larger discussion. Anything inconsequential.
How do you keep your mouth shut? Tape it up, if nothing else works. Try solitude, try to talk to yourself, so that you find a release for your mental words, the need to talk to others might dissipate. It worked for me 😊
