Native English speakers, what annoys you about US English the most?

Oh Absolutely... detest the corruption of pure grammatical English and the examples you depict. ,,, A lot of it is laziness and unfortunately with the advent of mobile(cell) phones and text talk the situation is worsening, especially among young people. It makes you wonder what things will be like in a couple of generations from now. .... Will English grammar, punctuation or spelling even be a subject taught in schools in the future as it will not matter to most people. Horrible thought.
