I've been semi rational my whole life, leaning less towards emotions. But I was always jovial and had some sort of reaction to events. Today I had the option to go to a lil get together/party in front of my apartment complex. Initially I did not care for them so did not go, I went to the party only when fists were thrown in the hopes to join the chaos and tell them to stfu as it neared 1am. Anyways, I didn't fight, I just wanted to be in the mix to see if I would feel something. My momentary excitement at the opportunity turned to nothing upon seeing the disgrace of men pouring out their feelings of dissatisfaction. I thought I'd feel sorrow or anger yet it never came. Later, a cute girl saw me and began to slowly move closer to me, grinding on me. I was turned on, yet so far away. I literally felt like I was watching myself from above and every action was calculated, every facial expression purposeful. Yet, I felt no acknowledgement for her or any of those who surrounded me. It was like I was alone surrounded by data. All the others who greeted me, some I knew, I had the exact same reactions. I have never felt so robotic in my life. Is this common?

Tldr: I've become colder as Ive aged and developed. Is that common?
