I am so sorry this happened to you! We can choose our friends but sadly cannot choose our family members. I feel for your friend & that she has to be associated with her cousin in front of others. She had to have been so embarrassed! I do think I woud tell her that I did not wish to ever have her cousin visit me in my home. I am finding that more people are the know it all type & can be very hurtful with their choice of words. I try to not have to be around those types as it just ruins my good mood. :D
