See this gif is beautiful, but it also makes me want to cry, because I look at it and I look at the expression on Sherlock's face and he is so damn young. Like for once he isn't this cold hard genius, he's a little boy with blue eyes and dark curls who doesn't understand, and you can see the vulnerability in him written on his face. I'm probably making a lot out of nothing but it breaks my heart.
