I only have praise for the idea of encouraging children (and everyone actually) to take action when they see something that could be improved. I think Meghan could be effective by focusing on this type of encouragement of others.
OK I'm going to totally derail here, but I recall an episode of You and Yours, Radio 4 consumer programme which featured a woman and her precocious 8 year old who had noticed a small error in the latest 1000 page Harry Potter book that escaped the proof reader's eye. The mother proudly explained how her daughter had written a letter of complaint to the publishers, claiming it spoilt her enjoyment of the book and demanding a full refund.
Honestly it gave me a massive rage which is why I still remember it. I just thought You awful, stupid woman, you're teaching your child to be a horrible person, a massive whinger going round complaining and feeling proud of it.
She's probably driving waitresses nuts in restaurants up and down the country by now.
I was brought up not to complain. We weren't allowed to complain. If I complained of feeling cold when out riding my pony my father threatened to sell said pony as soon as we got home.
I dare say there's a happy medium. I don't often complain these days but sometimes I'm moved to in some instances.
But generally it helps to treat people nicely and recognise that people are mostly working hard in difficult conditions to keep the heating on and food on the table.
Good manners and gratitude will always bring the best out in people.
Please don't teach children to be entitled whingers.
