TL;DR Made plans to meet up with tinder chick and she forgot and made plans.

Body: I made plans with this girl on tinder on Monday to meet up Saturday afternoon. She messaged first asking "do you really have a big ass?" Because my bio is "I bet my ass is bigger than yours" and then she said she needed to verify it and I set up a time and place to meet. Saturday 6 pm at the sculpture garden.

When I got there a little after 6 I messaged her saying to meet me at the entrance and then she said, "Oh my god I'm a horrible person I totally forgot and I made plans for tonight!!" I haven't responded yet. I am assuming she just made up an excuse for herself to make herself feel better. Probably won't respond and wait for her. Should I do anything more? Or just soft next her like I'm planning?
