Is AUTHOR wrong in the post ? POST : My crush, let's call her Rachel, is a national-level tennis player. I just met her at the beginning of this semester, since I moved states during winter break. I haven't been able to get an 'in' with her, so to speak. We're kind of casual friends that hang out at school, but nothing more. So I asked her last week (before spring break) what she was doing on spring break. She said not much, just teaching one of her friends to play tennis. I realized this was a chance and said to her, 'I've always wanted to play tennis, but I never got a chance. Can you teach me over spring break?' 

The thing is, this is a lie. What Rachel doesn't know is that my dad was a D1 tennis player in college and I grew up playing tennis, and was semi-competitive as a kid, but after my mom and him divorced, I really stopped playing and focused on swimming. But she doesn't know this because I just moved here a few months ago.

So basically, I told two lies to her: 1) I don't know how to play tennis and 2) I'm interested in learning. So far, it's going great. I'm playing the part of a beginner- albeit a good beginner- really well, and she and I are hanging out more. 

But I was texting a friend from my old school about all this, and he said it was a asshole move to lie to her. I said it was a harmless lie, and do think so.

So, aita, or am I in the right here?
