"I have made it a rule of my life to trust a man long after other people gave him up, but I don't see how I can ever trust any human being again"

This quote by Ulysses S. Grant talks to the problem of relying on people after being betrayed. Grant has made it a rule of his life to trust individuals even when others have given up on them, however he is now questioning if he can ever rely on another human being again. This recommends that he has been betrayed in the past and is now having a hard time to trust anyone else. It is a suggestion that trust is a vulnerable thing and can be quickly broken. It also speaks with the importance of being careful with whom we trust and how we deal with those who trust us. Grant's quote is a tip that trust is something that must be made which it can be quickly lost.
