Since there is so much food here, we can't not find something to eat.

When we open up the fridge, you see foods staring back at you but you just can't find things to eat. You close the fridge and after 1 minute you came back to the same fridge finding yourself standing in front of the food and the food staring right back at you. You close the fridge because there's nothing you want to eat.

People do this because it is either they are hungry but not. Or things in the fridge didn't impress from the person, in another meaning, they don't like the food in the fridge.
