Strange question

Why is there a light in your refrigerator, but not in your freezer?

Certainly, all of us have a fridge, we can see that the light is just in refrigerator, but not in freezer, that mean that we don't need light in this part of fridge. Normally, the door of refrigerator we open frequently than this from freezer. If we will have also a light in this second part of fridge we would have to pay more, because we use more electricity. This is just an extra costs, so I think that anybody would like to have it in their freezer.
