If you're going somewhere that you'd like to take pictures... like a wedding, a party, some sort of adventure... you'll remember to charge the camera.
But, remember to check to make there's a memory card in there.
Especially if you have a husband who likes to take your camera into the woods to check his game camera.
Because if you don't, you might go to take a picture of your friend at her surprise anniversary party...
And realize you don't have a memory card.
But you're in luck! You brought the back up camera!
Oh wait... someone took the memory card out of there too...
