I only have one child so that puts me in a reasonably secure place carbon-emission-wise.
Yes, he’s a wanker. It’s clear from the one about Rosie that the journalist can make the tone and the subject more sympathetic so I can only assume he was v wankery so the journalist chose to edit it in such a negative way.
To be fair to him, he’s 21, and that’s very young for a man. I know quite a few men who are decidedly less wankery at 40 than they were at 21. Especially with boasting about success and cleverness which often masked their insecurity. He may well improve, but he’s got such a long way to go to get to a good point!
