Hello and thank you for helping me yet again.

I was set to hang out with a friend and to meet up at a friends house.
I went. I waited about 2 hours for her to show up. She ended up being very late because of a movie and decided to eat at dairy queen.

When she was there she kept saying sorry over and over.
I left the house right away. She was going home too and we walk the same path. So we were by ourselves and she wouldnt stop saying sorry.
I told her to make it up to me. she kept asking how can she make it up to me. I didnt know what to say. So i kept quiet and said you'll think of one.
I didnt have a demand.

Questions:

Should I wait a day after to contact her?
Is her constant nagging of saying sorry a good thing?
