[90a top] Mishnah: Beis Hillel: Even if one’s wife merely overcooks and burns his dinner, he may divorce her.
R’ Yaakov Emden: Beis Hillel is not explaining a reason to justify divorce, but rather noting a reflection of the status of their marriage. If a man is having divorce thoughts because he is unhappy with his food, it is a sign of a much deeper/complicated problem.
D-E-ep Thoughts: Before we get upset at people, we must stop and try to understand what our emotions are telling us. Hashem uses others as mirrors to show us what is really wrong within ourselves. If we are able to fix our own flaws, we would not get mad/upset/annoyed at those around us. We should always use our encounters as opportunities for soul corrections and personal growth.
