Met this girl through a mutual friend who seemed receptive so I hit her up a few days later to tell her we should hang out tomorrow.

Her response was, "Why tomorrow?"

I never been asked why before, usually I get a "ok, cool" response or none at all so im curious of what others have done in this situation.

Edit: Thanks for the ideas everyone. I replied with "I have plans for the weekend" because its a good balance of boldness and mystery. I'll update when I get a response.

Edit2: Updating with a response from her : "Fun. I'll see whats up" Now I play the waiting game and work on other plates. I'll update as this progresses.
