Por que o parágrafo não se alinha ao lado de Imagem em HTML?

Estou aprendendo frontend web design e estou tentando criar um blog totalmente responsivo, como uma página estática.

Mas meu problema é que a imagem não está alinhada corretamente com o parágrafo.

Como o "Não se esqueça de acompanhar!" image deveria aparecer no primeiro post, apenas o conteúdo Não esqueça de acompanhar O conteúdo deve ser com Lorem Ipsum .. Mas está aparecendo com De onde vem.

Minha pergunta éPor que isso acontece? solução alternativa que eu vi aquiComo flutuar o parágrafo próximo à imagem sem quebrar a imagem? mas não entendi por que esse problema realmente acontece.

          <h2> What is Lorem Ipsum ?</h2>
          <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.
            It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages , and more recently
            with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>

        <h2> Where does it comes from ? </h2>
        <p>Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked
          up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus
          Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from
          a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original
          form, accompanied by English versions from the 1914 translation by H. Rackham.</p>
