There is nothing wrong Shirely as mentioned above. The verb here is " herumführen " and it is split into " führt ....herum" . This is a peculiar structure of verbs in German. " My grandmother always directs (leads) me ." " Mich" is 'me' , the object in the sentence. It is just in its correct order as the direct object. 'Großmutter' is Subject and the object being lead is the speaker "mich" !! (Notice: direct object /Akkusativ and therefore 'mich' not 'mir' )..

Nothing, the sentence is correct oO

There is nothing wrong with the word order. Just to double check, what you are saying is this: "My grandmother used to show me around" or "my grandmother always showed me around". The only way I can think of that this could be wrong is if you are using the wrong tense. If I were to say that my grandmother used to show me around, I would very likely use Perfekt instead of Präteritum, and thus use a different word order. This is because I find it hard to come up with a situation where I would announce that my grandmother used to show me around when it is completely irrelevant to happenings in the present. "Meine Großmutter hat mich immer herumgeführt, deshalb kenne ich mich hier aus" requires Perfekt. Similarly, "Meine Großmutter hat mich immer herumgeführt (und jetzt tut sie das nicht mehr, weil sie tot ist)", even if I don't actually speak the part in parentheses.

It's fine, don't worry.

Nothing. Who told you it was incorrect?
