They make a mess and I have to clean after them! I am the one to do the explaining to her!
They get/got themselves into this mess, I and the one to find a way to solve the problem. I am the one to handle her!
Of course, different circumstances here. And there are other ways and different situations as well.
I assumed that "levar com ela" would be "resolver o problema" since "she" (the landlady, the boss that is a woman, etc) is a difficult person. It may be that you meant something else, if so, let us know, please.
