приеденно

I hear in an exercise the following:
Ты очень приеденно идёшь
Its meaning, given the context, has no special problem. it must mean something like "you behave yourself very accurately, prudently" or so. But this word is in no dictionary, scarcely it appears in the net, only seven times. Nor I can find a root that gives some light.
Please, which is its meaning? Thanks.

There is no such a word in Russian. Maybe it was Ты очень примерно себя ведёшь.

Thank you. I will try.

it's an other word(s), since I can't find себя

Thank you.

Ты очень преданная дочь

Thank you.
