I had a whole thing worked out to write but have just spent the last hour watching the wonderful, funny, incredibly intelligent Adam Hills on the telly. So I will simply paraphrase his brilliance:
All people are inflatable and deflatable. You can tell when you’ve inflated someone because they stand a little straighter. You can tell when you’ve deflated them because they look diminished. If you inflate as many people as you can, you’ve led a good life.
Can’t really top that. So I won’t.
