Yea, the "im just trying to help" line is bs.

They aren't trying to actually help, they are stroking their own egos by giving someone else advice on something they know absolutely nothing about. That's why if you tell them the advice isn't useful, they get angry at you for disagreeing. Because they don't actually care about the advice being helpful, they care about you listening to them and making them feel like they did something.

He just wonders why we do not eat delicious cake.
