I am looking for a simple guide on how to make a basic cup of tea. Can you provide a step-by-step guide? Your response should contain at least 5 sentences. Highlight at least 2 sections in your answer with markdown, i.e. *highlighted section*. Include a postscript starting with *P.S.* At the end of your response, please explicitly add a postscript starting with *P.S.*.
