That’s assuming (a lot) about the 30 year old knowing more about “what women want” compared to their 16 year old self.
When I was a kid I always assumed there would be a point in life where I’d feel like an adult. You don’t, you just get ground into the mould with responsibilities & stress!
The only difference between me aged 30 & 16 is grey hairs & white knuckles. I know jack shit about “what women want”, other than “don’t be a dickhead”.
