Yeah, I remember these interactions, I even thought of taking it as an example but preferred not to. Anyhow, I think I can understand Canadians... and you, Americans. (National) identity is a very important thing - and it`s one of the reasons we Estonians want to be acknowledged as a completely separate nations, we have fought for it for a long time (forgive the cheesiness, but you get my idea). I think the same can be said about Americans - you want to be acknowledged as Americans and not just a punch of European immigrants with a 400 year old history.
Oh, and for your further information, Estonian language is related to Finnish and Hungarian (don`t ask me how, but it is), whereas Russian, Latvian and Lithuanian are "fellow" languages.
I must apologize for the late answer; I`ve found that going to an art school is not all a walk in the park, we have a lot to do and a lot ideas to generate so...
