I'm thinking of refusing to pay my brother back for "damage and lost income". When I was baby sitting  his kid set off a can of bear repellent (mace) in his Airbnb. To me he left something very dangerous in the reach of kids.
What? This story is crazy! Would he do that on purpose?
Yes, he did that on purpose. He is clearly trying to sabotage my business.
If someone damaged property they should pay to have it repaired. You should make sure to watch kids closely so they can't get into trouble.
Yeah I should but if I am making a business out of this it shouldn't be my responsibility to deal with kids.
If property was damaged then it doesn't matter what excuse the person has who damaged the property, they need to pay to whoever's property they damaged. Does this not make sense to you?
