You could say, for example. 'I broke the light and I got away with it. My mother thought it was the dog that had broken it!. This means that you did something bad but nobody knew it was you who did it, so you weren't punished. Is that what you wanted to say?

It isn't quite right how you have used it. You can say: I broke the light but I got away with it. Or more a complex way: I broke the light but my mom let me get away with it. Mommy is what small children say. Given you are an adult I would advise you don't use it.

If you mean with then it is right

With or from?
