This is it!! What I consider sunrise is the blue hour when the light starts showing up and I know it’s a new day. I can start seeing the surroundings and hear the sounds of everything waking up. What I consider sunset is the golden hour when I know I have just a few minutes left in the day. I hear things winding down and know that I wont be able to see much anymore. That’s why I perceive them as differently. The cue I used to notice them is their initial impact, so that’s what I associated with it. I knew I wasn’t crazy! Thank you very much :)
