Well in our "group" of friends there are 9 of us but there is this girl who everyone seems to be annoyed with.She isn't a bad person and she can be nice.However she follows people about ,or joins the group at lunch or whatever and doesnt speak at all .There has been multiple occasions where I've just been standing and just asked " where is ......?" ,*otehr friend*" erm she is behind you" or you just turn round and let out a shriek as you dont expect someone to be standing behind you.Also we went to a gallery and i noticed she was following me so i got a friend to check if she was doing the exact same ,she was when i stoopped so did she i changed direction so did she .That was a very uncomfortable day i couldnt even text my mum as she read over my back or walk awy for tiome alone because she followed ,yesterday i was told by a friend waiting for me she walked into my toilet cubicle then stepped out went to turn and lock the door.Im sorry for the long message and it probably doenst make that mcuh sense but it is beginging to kind of get distressing and im sure she doesnt mean it or she doenst have the confidence but what can we do ?She is making the rest of the grouop hate her for it .
