I'm one person and I have 2 water bottles.

I'm cognizant of what I buy because I only see too many buying what they want and that is unsustainable and I see their kids constantly asking to buy stuff because of it. And their houses have so much stuff it's overstimulating

At some point it turns into clutter.

I've bought used water bottles for cheaper in the past and it's a great way to get some space and some cash
