Friends and coworkers think we should get together at the bar regularly for drinks as a girl's night thing and although it sounds nice I can not afford to go. Is it rude or should I trust they understand. I had mentioned once before and heard oh it's only a couple drinks and another girl said I ll buy yours, but I don t think that is fair unless I can return the favour next time, but that wouldn t be the case. What is the right way to go about not seeming rude but not trying to end up never invited again either?
