As parents, teaching your children about the importance of sharing is a vital lesson, but many parents will also ensure that their little ones know that they don't always have to share when it isn't appropriate to do so.
But one mum has been left furious after she was told by a stranger in a park that her son would grow up to be "entitled" because he wouldn't let another child play with his toy - after they stole it from him.
The woman, named Corrie, explained in a video that her son had brought a toy truck with him to the park because he enjoys playing with the gravel.
