Your wife is pregnant and she told you to bring Blackberry jam for her, because that's what the baby wants. You looked in every shop but there was none. Then it just came to your mind: the three bears' house. They love blackerry, so they must have some at home. It will be very dangerous if you get caught though, but you'd give up everything for your wife and child. You cautiously waited till they left the house. Wow, it's not that big as you thought. No time to wate, collect blackberries for the jam and leave before they get back. Good luck!
