I am talking to a girl on snapchat right now who added me off tinder. She told me she's sick so she won't send me a snapchat. I told her to send me a snapchat when she's feeling better. Her response was "We'll see lol"

I am certain this is a shit test. What is my best response? I have gotten this response many times from tinder girls when discussing meeting up/going on a date/sending me a pic, etc.
