Like you, I would suspect she is a bsb. There are just so many out there.
I was in a nightclub the other week (not clubbing but promoting), mingling around with people and for some reason the subject 'Dogs' came up (I love dogs). This slimey guy turned around and said 'you want a dog? I can get you one, what kind do you want?'. I would hate to be judgemental, but just one look at him and I KNEW he was a BSB, or at least have friends who were - I looked at him and said ''A Pug?''. He was like ''a what??'. A pug, I said. He said Oh I don't have any pugs (''I don't have any pugs''!!!) - I've got Rottweilers, Staffs, Pitbulls, Alsations - you can have one, for free.
I just said no thank you and walked off, it was upsetting to hear.
