The worst part for me is mixing sayings and the construction of sentences. I've never been that good at English grammar, but after using English more and more, my grammar in my native language have gotten worse. I'm half way in a sentence, in my native language, before I notice I've started on an English saying, but directly translated to my native language and it makes no sense. But, there's no cow on the ice, as you say, because my wife and I are like pots and pans, as you also say; we are the same way.
