I haven't always felt this way about Summer daylight hours. I can remember when I was 6 feeling annoyed that I had to be put to bed when the sun was still out because when the sun is out it's still day, and daytime is for play, not for sleep (my bedtime was 6:00 back then).
Over the last week or so I've noticed the sun setting a little earlier than it has been. I always have felt sad about this change in daylight hours. I do not enjoy winter. I find it cold and bitter. I hate the cold, I hate the rain, and I hate the dreary grey clouds. When the sky is chock full of drab, grey clouds, the world looses brightness and colour. The sun setting earlier is a very obvious and small reminder that winter is coming. (I know it's technically not coming for like 6 months, but, last year the temperature change/ overcast days came prematurely)
It also means I'm overestimating how long I can leave shooting my outfit, causing terrible lighting situations (Sorry!)
