A paradox for Father's Day

On this Father's Day, a daughter gives her father a self-painted picture that her father has long wished for. The daughter says: "I am giving you the picture that you wished for, and my gift will be a surprise". The father trims and reflects on the truth of this statement.

The statements "I'm giving you the picture you wished for" and "my gift will be a surprise" are obviously not both true at the same time. This means that the father gets the picture he wished for or he doesn't get the picture he wished for, which makes it impossible for him to predict. Thus the daughter can joyfully give her father the picture he wished for as a surprise.
