Why people do this.. Say they going to come see you, & when you reply if you going come see me then stop saying it and let it happen.. So they replied " I could say whatever I want if you have a problem with it then that's your business" 😑😑 not understanding who cops an tude about something simple as that when its the truth, dont keep telling people you going to see them if you have yet to do it..
