How could I laugh at you! Put another way

Another way of saying it is "I won't laugh at you."

"I won't laugh at you" is a more direct way of saying it, and means the same thing as "How could I laugh at you". It's a good idea to use more clear and positive language when showing respect and concern for others. Overall, the clearer, more precise, and more constructive ways we express our thoughts and feelings promotes better communication and understanding.
