I've been watching Alice Fraser's Savage. (It's good! But don't expect a non-stop stream of laughs: it's about the more difficult aspects of life.)
At one point, she asks (paraphrasing) if you can remember what it was like to be three years old, eating an ice cream in the sunshine, shirt off with the ice cream slowly dripping down your torso. I can't – I don't have all that many clear memories of that part of my life. Fortunately, I don't have to remember: I can often see with my own eyes what it's like to be three years old and covered in ice-cream. Heaven.
