pmsl you lot!
Not sure I'd admit to being a Chatham girl. Would rather be considered a London girl (wheree I've lived most of the time I haven't lived in Chatham) or even an Essex girl (born in Colchester) in preference.
Now, I wasn't posh enough to go to CGSG or Fort Pitt but I did do my A levels at CGSB and was head girl! Does that count?
Although, I did once get thrown out of Maidstone McDonalds for instigating a milkshake fight. Oh goodness, my identity is all over the place!
