Help me out

Asked a girl what her plans were this weekend. She said she didn't have any so I asked if she wanted to hang out. She said sure and asked what I had in mind, so I listed off a few things like watch a movie play games chill etc. I followed up with asking her what she had in mind. All she texted me was this picture of an empty pitcher of water... I responded with you want more water? And now she's not talking to me. Did I miss something here?
