I have a friend and she never wants to hang out. Not just with me but our other friends too. She's alway like "let's hang out this weekend!" but she never does. Or she'll stand us up. Like me and another friend asked her to hang out with us last weekend and she said that she would meet us at a movie at 7 so we went and we waited and it was 7 and we called her and she said "she forgot and she couldn't make it" we don't know why she does this but she does it ALLLLL THE TIME! It makes all our friends so mad. She always makes up an excuse and we can't figure it out. Any ideas?
