My brother recently brought home a new girlfriend.He met her quite quickly after being with someone else and she is keen to make her mark very quickly into our family! Myself and my partner dont know what to make of her and in family situations I do find her very bizarre and abit odd. At Christmas she came over for Boxing day and to be honest did spoil the day! The trouble is she just doesnt have a a clue about how loud she is.If someone cracks a joke she always lets out this huge great big laugh which takes over the whole room.At first I didn't notice this but then I became more aware of it and it sadly does annoy me abit.She is also very one sided and just talks ( which is fine!!) but its always just about herself and what she has done, she doesnt enquire or ask information to make the conversation go to the other person. I had only met her for the second time on Boxing day and she was telling me her life story and some quite personnel info about ex partners.I was shocked as I guess i wouldnt behave like this with a new family.She was also talking about having children with my brother and weddings (they have been dating less then 6 months) She got very drunk on Boxing day and was over powering, everyone noticed it.She made a bee line to speak to my Dad, then Mum when they were alone and was keen to express how much she loves my brother.Around the dinner table she just talks at my parents and I do feel sorry for them as they have so many great experience and tails to share, she always manages to switch the conversation back to her which becomes so boring! You dont even ask her a question and she just talks and talks (very loudly!!!)...... She left her make bag in our family bathroom over Boxing day and she also left out some prescription tablets for citralopram and propranolol openly for people to see. I am unsure what these are for but surely you would keep things like this out of the way? Today we had anotehr family event and again she was loud and did start to get annoying. I myself am quite loud but this girl is in a league of her own.Any small joke and she is there laughing her head off in the most high volume explosion.She just talked at my Auntie and Uncle and again old them her life story!!! Now I am worried I cant be around this girl, something just doesnt seem right about her and I feel like abit of a cow for feeling like this towards her!?
