Why do you think gilgmesh is unwilling to take siduri advice at this point in his journey?

Gilgamesh may be unwilling to take Siduri's advice because he is reeling from the death of Enkidu and seeking answers to his questions about life and mortality. He may feel that he needs to find these answers on his own and is resistant to the idea of seeking guidance from others. Additionally, Gilgamesh's pride and arrogance may also be preventing him from accepting advice from someone he considers to be beneath him.
