Hi Jolly ,
I agree with nadya and onekindman , in what way do you mean , if this lady has not asked for money or even insisted to meet you in your country , then it will depend on what you mean by unusual and secondly if you are willing to put up with it . There was this woman that i had writen to and is still on the site i believe , she was ecentric to say the least and called me sweetie on the first letter , btu it does not mean that something is wrong or strange about her , it might just be the way she writes .
