WORDS

The words “shouldn't” and "can't" are funny words if you think about it.
They are words made up of two completely opposing words. The first part “should” or "can" means that something should happen and that something can happen.
The second part “not” means that nothing should happen and cannot happen.
Since your mind actually think in images (even if you think you are not a visual person) there is no way you can create an image of “shouldn't” or "can't"
