Grandpa just died. Can the grandson get a haircut?

Of course. Because grandpa is the elder of the whole family, the most respected junior, and the apple of the eye of the whole family, now that grandpa is old, he has to do anything for grandpa, such as washing clothes, cooking and cleaning, regardless of whether his grandson, son or grandson can cut his hair. These are all things that future generations should do. So the grandson will cut grandpa's hair.
