Lizzie displays great enthusiasm - perhaps even to excess - this can definitely get up some people's noses. From the little observation I have had of her on this place, she also does not accept 'correction' lightly - she see it as 'attacking criticism' - and then pushes harder to 'justify her ignorance' of things others know from experience.

I knew one other such female person who presented herself like Lizzie - she was not as clever as she thought she was - she tried to pretend 'I was her boyfriend' - and spread that story all around - which took me great effort and much pain, because people also believed 'that I was being nasty to her - as I said she wasn't as clever as she thought, cause I guessed that she wanted to move in my house with me, and was able to drive in a different direction when she persuaded me 'to pick her up' - seven suitcases was a bit of a give away.... :-)
anyway she jumped out of the car, and the last I saw her, she was being picked up for her own safety by a police car....

If 'Sam' wants to associate himself with Lizzie, that's HIS business.

I have developed over the years an increasing spelling hassle while typing - without ieSPell, I can't even SEE the typos at the time - it is a physical disorder - and I can't use other browsers, cause they don't allow similar useful plugins I need....
