From Ajahn "The Super Monk" Brahmavamso #3
2 sisters comes to Ajahn, One begins to complain about the relationship with her husband (Well, if you read the previos post, maybe its not a relationship afterall), and wonder if she should just have a divorce.
The other one said how lonely she was for being single for her age, and hope so much that she could have a relationship with someone.
The 1st thought: "This is easy, just Swap!!!" everyone laughs.
Ajahn turn to the 1st sister, "Look, when you are married, you go through the married suffering, if you get divorce, you will get the single suffering, look at your sister." The same goes to the 2nd sisters.
The lesson is, "When you jumps from one situation to another one, there will be new suffering, the problem is not solved, you just jump into another kind of suffering. The only way out is that you could live in peace with it and look at the positive side of it." ... which leads to the dog's poo story:
"You are walking on the street, and suddenly you just realized you step on a dog's poo. What should you do?" Ajahn continued, "you take the poo back home and cover it under your mango tree. A year later, you just found that the mango is sweeter than the previous year. Instead of blaming the dog or the owner who lets it do so, you take advantage of what is happening and seek out the positive side."
