One day, you, Sherlock and John were sitting in the living room, chatting about various topics or exchanging jokes and sarcastic comments. Everything as usual. This time, you made tea. Watson hardly noticed the difference between regular tea and another one. John drank it calmly, but Sherlock, for some reason, did not drink it, but no matter how hard he tried, did not emphasize it (due to decency and not wanting to spoil the atmosphere of a pleasant conversation). But you still did not understand the reason, so you looked at Sherlock with bewilderment while he tried his best to smoothly divert your attention to a more interesting topic than the tea that was not tasty for him*
