Hi Doodle.
I don't have grandchildren yet, but I do remember thinking that all my friends had a much better time than me, and that they were allowed to eat cake for breakfast, or stay out late, depending on how old we were.
On the whole, this wasn't the case - but everyone pretended to be 'cool' and didn't admit that their lives were boring too, and their parents were massive killjoys like mine .
I think that maybe social media makes that seem worse, but I doubt that things have actually changed much. People only post (or even take) photos of themselves having fun, and looking good, not sitting with a face pack watching Eastenders. If you haven't already, you could point this out to your grandchildren?
