The major reason why people often don't give their trust so easily to someone is cause of a past experience. I think limiting one's high expectation from a person will help to avoid oneself getting disappionted and we should also not shut down one out cos our instinct says so.
We should try and give everyone the benefit of doubt cos the person we trust more may be the one to break our trust and those we trust less may end up being trustworthy. I think what we ought not to trust is our instinct cos it might be misleading
