The context of the following conversation is Kendall was really into house plants and often pour water in to jars so the fluoride would evaporate out.:
Kendall says I was really into house plants.  I want to put a plant in every corner of the room..
The friend responds You have a green thumb..
Kendall responds My mom was like that so I learned to take care of plants from her.  She often poured water into jars to the fluoride would evaporate out.  That's suppose to cleanse the water..
The friend responds That's a neat trick..
Kendall responds I end up doing the same now.  I have jars of water on my table with fluoride in them..
The friend responds What are you going to do with them?.
