Can I chase 2 1 girls at the age of 28? But she said that when I was old, she would call me uncle.

I believe you can. It's just a joke to say that you've been here. Don't take it too seriously. She's just not ready. Calling your uncle shows that you look mature, and it is also a kind of intimate address, which shows that she doesn't hate you so much. As long as you work hard, it is not impossible to be self-motivated. Come on, let her see your goodness and your warmth.
