Pictures, especially good ones, can be devestatingly sad. They can hold within them every emotion ever felt in a moment. They can be a step into a past that is gone forever.
But the important thing is that pictures remind us to live in the present and be grateful for the small things. A photo can last forever but the seconds, the minutes, the months, they come and go. They last only an instant and once they’re gone you will never get them back. Be present, be aware, and be appreciative. Live in the moments before they are memories.
