So theres this girl that I'm taking to prom and I've been playfully teasing her and shit but yesterday she texted me something that had me confused, maybe one of you guys can help out.

Her: you gotta be nicer to me

Me: ??

Me: What are you talking about

Her: you heard me

Her: read my text*

Me: When have I not been nice to you?

Her: idk you just have that idgaf vibe

Her: sarcastic af

After that I didn't reply. I could see what she meant by sarcastic af because that's my sense of humor and I do it with everyone but unsure by "idgaf vibe"
