We’ve all got one - that mate who went from troublemaker to muffin-baker.

Come, let's resent his happiness.

1. They seem to be at a wedding every other weekend.

2. He didn't come out for a pint for a reason related to his cat.

3. If you Whatsapp him after 10PM, he's consistently fast asleep.

4. He now says 'We' instead of 'I', like some kind of creepy pod-person.

5. He treats his other half getting a cold like a nuclear meltdown.

6. He's been to IKEA. Twice.

7. He's been spotted doing this.

8. He never talks about sex any more.

9. They're un-ironically rocking #DadShoes

10. He's developed a broad knowledge of Saturday night TV.

11. He seems happy and content, and that kills you inside.
