I have come to a conclusion this morning.
I have never liked grapefruit. I've never been able to understand why people enjoy eating it—but this morning I realised I didn't actually know why. So there was some Ruby Red juice in the fridge, and I poured myself a small glass and tried it to find out.
Now I know why.
It's so disgustingly bitter. It's almost identical to the aftertaste you have after you vomit.
