The Emotions of Photography

I've been doing a broad look at my photographs stored in Lightroom today and noticed every now and then that a quick smile would come across my face.  A photo taken as long as a decade ago would trigger that smile - a place, a person, a sunset, a scene that brings back great memories. The photo might not be the greatest in the world or even in my world but that doesn't matter.  Not all photos - or even most - are destined for the wall or a blog.  They're just there for the memories - and is there anything better?
