pencil's cutting

Traditional pencil lead is as long as the pencil. When the pencil is used, the last part of the pencil usually throws away by virtue of its inconvenience. People always try to use it up to avoid waste. Otherwise, they would be regretful. Why do pencils make people unhappy when using them? The conceptual pencils have shorter leads compared to traditional ones so that people can throw them away when using them up with a better mood.
