My father was a stern man, the type of person who doesn't like to show emotions openly(i did not see him shed a tear when grandfather died), but I begrudgingly admit that he did give me good advice on life. The best advice he ever gave me was to never trust people so easily, be extra careful who you talk too and to always be prepared for the bad things in life(it might seem like a very pessimistic view and it is, but it has really helped me deal with all the conflicts of my life so far).
