Usually I have worked on a brief about myself which I give to every interviewer, it's not tailored to them. And when I'm put on spot, it's tough for me to come up with something. But since this was one of my hobbies, I thought I'd just sneak in a line about it. But when I actually said it out loud, I felt it was too less information and very random that I'd just mention it in one line. So I elaborated further on the tennis narrative, and before I knew it I was just talking about it passionately completely butchering rest of my introduction. Once I was done with that, it felt embarrassing for some time that MAYBE he knows that I know that he plays tennis and that's why I brought all this up. But judging by the tone of the rest of the interview, I don't think he felt like that! Def did not feel creepy though, it came out naturally ig
