Description: screenshot of Tumblr with two posts. One describes how Sherlock Holmes would figure out you're trans before you even do. The second describes how Hercule Poirot would figure out you're trans after initially suspecting you of murder and then clearing you're name. Then he gives you a kissy kiss.
...and then when you look confused [Holmes] is like "ah... had you not arrived at that conclusion yet?" and wafts away... leaving you in a gender crisis
Of course, Holmes knew perfectly well you hadn't figured it out yet -- that was the most obvious deduction of all. He deliberately broke the news to you for his own amusement.
