Simply put, because you will cherish them one day.
More than once I have had a past bride call or email me thanking me for the picture of a grandparent or family member I took at their wedding because soon after said grandparent or family member had passed away. And the picture I took at their wedding? It was one of the last of them. I don’t need someone to tell me that they are going to treasure that photo for the rest of their lives. I know. That responsibility and gift I am able to give them is one I don’t take for granted.
I had a brother pass away a little over ten years ago. About six months before my mom dragged my whole family (Mom, Dad, my two brothers and myself) to a studio to have an updated family photo taken. None of us were happy about it (except my mom), but today that is one of the most cherished photos I have because it is the last family photo we have of all of us. To this day, my mom still tells me how grateful she is that she put up with all the complaining and made us have it taken. I’m grateful too.
Go get a family photo taken. Even if it’s just you with your husband or significant other. You never know how much you might cherish those photos now and later.
Here’s said photo. I can’t believe I’m posting it online for the entire internet world to see my bad hair, but as I said it’s an incredibly important photo to us. Please excuse my bad posture. Rest assured that if you chose me to document your family memories I’ll fix bad posture. 😉
