Doubts are always about something that is positive.
If someone tells you, 'I love you so much', what do you say? 'Really?'
If someone tells you, 'I hate you', you never say, 'Really?'
We doubt in the honesty of a person, but we never doubt someone's dishonesty
An intelligent person turns this around, and starts doubting the negative.
