OMG I sooo pissed off!!! sorry

Ok.. I get an email today from one of FH cousin who was on our guestlist with a guest along with her older sister and a guest, we dont even really keep in contact with them except when we run into eact other or whatever. Anyways these 2 sisters have a sister who lives out of state whom with FH doesn even keep in contact with, well this sister practically invited herself along with a guest. So in the email shes pissed off saying that they are all coming with a guest and that the out of state sister switched her vacation around just to come to our wedding and that shes bringing a guest but in the end its my wedding and I do what I want... ....I replied telling her 'well Im sorry but we had a limited guestlist in which we only invited friends and family who we are close with and keep intouch with and that to begin with that sister wasnt even on the guestlist but if she wants to attend then its fine by us but as far as her guest Im not sure, and sorry if she had to change her schedule around, but she needs to understand'.. ... OMG Im soo pissed because in her email she had an attitude and was pissed off, I felt like saying 'You know what youre right its my wedding thats why you are uninvited' but I couldnt because I dont wanna cause conflicts you know. What would you have done???

oh these people
so sorry
Yknow...it sounds like everyone has a few no-shows, maybe say yes and keep your count the same, if you think you might have last minute cancellations.
