you`re right. I want to become - english native speaker. Well... surely it never could be, but... when i ask my friends about how to say something, they answer me something like - compare past perfect and past simple. and i thought - Daaaaaaamn )))) it`s not the way i want to speak english ))) certanly, without knowing rules, we couldnt even start. But speak (speaking) when you always must sorting the rules... - become a talking machine )))) Wow... talking machine ))))) funny

Most English people have no idea what all the English verb tenses are either, or what the rules are for when to use an article and when not... we just do it without thinking about it! Which is one reason native speakers aren't automatically good teachers.

well... i forget to say - you doing good ))) and also wonder for me - you have a russian keyboard ))) i do not know, what is prepositional and accusticavetate... damn... something... i am not sure i know it even in russian, but... энивей ю нид - ю кэн аск ми ))))

Спасибо! Алексей, я понимаю. I have studied the contrast between prepositional and accusative case, but it is still new to me. Thank you for the feedback!

Я (что делал?) ездил (куда?) в Латвию и в Эстонию. или так - Я был в Латвии и в Эстонии. ездил - (куда) направление(direction) (в магазин, домой, к другу, гулять) был - (где) место (place). (в магазине, дома, у друга, я гулял) надеюсь, это поможет. Хотя не уверен. Я не учитель, просто хотел объяснить. i hope it will help you, but i am not sure. i am not a teacher, just want to explain.
