Or maybe they have some "profile writer" in their "staff" who writes it? There is nothing wrong with making mistakes when it is not your native language.
After all, English is not my native language too, and as you see I make mistakes too. Just enter in quotes: "I the sociable girl", or "I the cheerful girl", or "I the nice girl", or any combination of those and here you go. I bet most of it will be either from Kazan, or Cheboksary, or Yoshkar-Ola, or... But sometimes they are not so stupid, and copy the profile descriptions from somebody else's profile, written in a good English.
Like this typical scammy profile description: "I have very bad marriage experience. First of all, even if everybody around her was indeed a drunkard, why the hell she would put that in her profile?!
Besides, not all Russian men are drunkard, but probably those from her own social circle.
Like any woman I am fond of talking but at the same time I am a good listener. I suppose the man should be the head of the family.
