I have a friend who is great, fun, interesting, kind. But she is literally late to everything...if I say meet between 7.00 to 7.30 she will arrive at 8.15 ...Or ask to change the time at 7.25...I can put up with it to an extent if I am in my flat but it's when you're waiting to do something like this evening outdoors and instead of doing it in daylight your going to do it in the dark. She doesn't have reasons other than just not getting her act together. How do I mention this or should I suck it up?
