When the "nice" computer genius from my best friend's family landed as an intern and became my subordinate, I thought that I had a capable person, but I didn't expect that he would "invade" my project step by step, gently but firmly, and also break down the inner wall that I was guarding against.
"Sister, I'm very good"
"Sister, you are not good"
"Sister, can he live with me?"
"Sister, tell me how nice it would be to tie you to my side."
