If you're raising your children to follow a vegetarian or vegan diet, then you'll know how important it is that they eat the right foods when they have a meal you didn't cook - such as at a restaurant, or at while at a friend's house.
And one mum has been left outraged after she discovered her vegetarian son, Alex, had eaten a meat pie while at his friend's birthday party, even though she had told the friend's mum about his diet.
Explaining the situation online, the mum of the 10-year-old birthday boy said she had been told about Alex's vegetarianism and had supplied veggie dishes for him to eat, but after she served the food, she noticed the youngster was tucking into a meat pie.
