Hi , long story short,me and my cousins birthday is on weekend . Mine is sat hers is Sunday , she wants to go out for hers on Saturday with some of her mates and invited me . My issue is that I don't really fancy going out , it's my day and I just want to spend like a day out with family and some food . I don't really want to go out drinking . Also they are going out to one place I particularly don't like ,I feel too old for ,but she likes that place. Anyways she can do what she likes but then I don't want to ,it's actually my birthday. I think lots of girls are not coming , and now she is on my case that I need to come but I really don't want but I don't want to be rude and fall out . I kind of feel she only now begging me because there is barely anyone coming . So not sure how to politely say no ?
Also I have told her that I don't have so much money to spend on night out ,I rather spend that money on smth else x
