It's the conversation every man who has a daughter dreads. The boyfriend conversation. 

Though most men would expect to be able to put it off until their precious little girls have hit double digits at the very least. That wasn't the case for Scottish man John Tierney who was 'forced' to lay down some ground rules with his four year old daughter Grace after he caught her waving at some boys who passed them in the car. 

While we seriously doubt that John will be this tyrannical about his daughter's dating life becomes a reality years from now, it looks like Grace will be more than a match for him regardless.
