Met this girl in a store and 4 weeks later again in another store.

She gave me her number without me asking. Would say she is a 8/9.

I texted her to make dinner together. She said she thought that was a super nice idea and asked me which days I was available next week.

I told her wednesday and saturday.

Now day later, she text me 'she forgot' she can't next week as she has to prepare for school stuff which is the week after that.

But after that week, she has certainly time.

Is this a test? I hate these tests. How should I react? What is she trying to test here?
