Met this girl on tinder, chatted on there for a bit then moved on to Instagram the same day. I slipped in there while texting the idea of meeting up and she responded pretty positive. Today I straight up asked her if she has any plans for Sunday and that we should meet up then. She then says that has work on Saturday and she might be too tired to go out. (she works as a part time waiter at events since we're both teens). How should I proceed from here?
