I have been with my boyfriend for 2 years now and we're very happy together. Only one thing, his sister is and always has been utterly foul to me. When were alone I try to start conversation with her and she throws one-worded answers back at me. She never says hello or good bye, nevers smiles at me, NOTHING. I also found out the other day she was responsible for starting a vicious, completely false rumour about me last year.
AND she even asked my boyfriend to not bring me to her pub again (shes an assistant manager at this pub), to which he told her she was being utterly ridiculous. How on earth do I maintain my cool around this girl??
