I'm 32 this year. The older I get, the more I feel that my speech unconsciously carries a hint of old-fashionedness.

In the past, I called classmates, young ladies, and beauties;
Now my catchphrases are: "Little sister, let me tell you!"
You can imagine why young girls nowadays are breaking away from old-fashioned guys—it's biological aversion. But old-fashioned guys have money, so the money they spend on being old-fashioned goes to young handsome guys.
I consider myself not too old; although I'm 32, I interact quite a lot with young people and like to learn about trendy things. But when people reach this age, it seems they unconsciously develop a paternal tone, which can feel quite awkward.
Question: For girls around 2000, how can I prevent young girls from breaking away from me like an old-fashioned guy? Can everyone give some advice!
