Made a post last night about a girl I met on tinder and taking her for a drive. Went well, got the kiss at the end of the night. She told me that I should text her, I waited until she text me. My responses were short. She said it seemed like I wasn't interested anymore. I said "Yeah. That kiss wants a word with you."

Her: "what's that supposed to mean ;)"

Me: "I'm exhausted and going to go to sleep. Text me tomorrow if you want."

Her: "Will do. But I'll still have that question in the morning."

Sure as shit, she texts me right when she wakes up at about 1030, I'm at work. I responded a few hours later, and have sent a couple messages since then. She told me she was having a new years eve party and that she wanted me to come. I said "We'll see.". A little bit ago she hit me with: "So what about that kiss"

Me: "Haha. So how was shopping." (She told me earlier she was going shopping.)

Her: "Don't avoid the question."

Me: " I don't have to answer that."

Her: "Why not?"

And now I'm not sure what to say. I was thinking if something like "That's on a need-to-know basis. And you, don't need to know." But I'm not sure if that's wise. What do you guys think?
