I am constantly being shamed every time I use plastic.
If I buy a plastic bag at a store or even when selecting food items I am judged, given the side-eye and told - rather loudly and without hesitation - that I am making the wrong choice.
You see, my 9-year-old has no filter.
He tells it like he sees it and is quite happy to call out something he regards as wrong no matter the time or place - and this includes using plastic bags.
While at the supermarket the other day I went to throw a 10-pack of potato chips into the trolley for school lunches. The kid piped up and told me I was making a huge mistake for two reasons; 1. It was better value to buy big bags and ration them in reusable containers for lunches, and 2. It was better for the environment.
