"If you are in a beautiful place where you can enjoy sunrise and sunset, then you are living like a lord."
I think the two people on the left side of the bridge are taking snaps, as sunset is the best time to take snaps because we don't need any artificial filters, during sunset the nature is at its best, I also think that these two people are couples because taking snaps of each other at sunset is what lovers do. What do you say about it?
For all you hopeless romantics out there like myself, the real reason why we glorify these instances of beauty is because they are simply that… idealized romance. Sundown seems to embody the sheer power of an utterly romantic point in time. Just like love at first sight, it takes your breath away, leaves you speechless and if only for a moment, slows down time. In that instant, you feel the love and gratitude for Mother Nature exude from every inch of your body. A sunset possesses the promise of a new day. With the sun’s last rays peeking out from the horizon comes the realization that tomorrow holds endless possibilities. You know it won’t last, but you savor every last bit of that fleeting beauty.
And the one in the right side is enjoying the nature, I think he had a busy day and is tired and now he is relaxing his mind as well as his body to prepare himself for the next day which will again be challenging for him. I also think that this man loves loneliness as he is not with anyone, often people enjoy senset with their loved one's, but there are people like him who love to relax there mind and enjoy the nature on their own.

This is one of the moments I have shared with my friend during sunset, this moment was quite relaxing and Nature was at it's best
