Ok, well yesterday I was talking to one of the girls Im gaming, we work togethor so I see her pretty regularly. So we are alone together working, and I dont know how, but the conversation went to her calling me. And she was like "im going to call u every day and ask u about your summer haha" and I was like "ok, im going to hold you to that" and she was like "ok ha". The day ended on a very high note, me getting off work while she was still on break, and her begging me to stay with her until her break ended. (I left before she got off her break, just to leave her wanting more, didn't want to make it seem like I had nothing better to do)
So she texts me that same day in the middle of the night saying something like this. "I just took a myspace quiz saying what ethnicity I should date and it said (my ethnicity) hahah

" So i said "you shouldn't ignore the signs haha" and we talk a little bit. But then I brought up her calling me and said: "Im going to be expecting that call" and she said "oh you'll get it!" and I replied "haha im sure,...."
Well to make a long story short, she never called the next day. Am I overeacting, should I just forget about this? Should I bring it up in our next conversation, what should I do?
