My friend, always remember one thing in life that one should not trust anyone too soon. Many people come in our life and we think that they are trustworthy but it is not always so because many times they come just to use us and not for anything else. One should not trust anyone except his blood relations. If you have been with a person for a long time and you feel that he is trustworthy then only you should trust him with open eyes otherwise today's world is selfish and thinks only about benefits.
