When Nathan was a baby, he didn’t have any toys. He did, though, have a bear that made heartbeat sounds and a bassinet that could vibrate. Both of those used batteries (duh) and needed a screwdriver to open the hatch to put new ones in. When I needed to replace the batteries, I’d get the screwdriver from the garage, replace the batteries, and put the screwdriver back in the garage.
That worked well, until the time all the batteries died in the devices right at bedtime, and we needed those suckers replaced QUICKLY, while he was still SLEEPY! The garage is at the other end of the house, too much time was wasted in traveling there and back, and by the time the batteries were in, Nathan was screaming. *sigh* After that, the screwdriver had a permanent home on our dresser 
Once Nathan moved into his crib, he had mobiles that made soothing sounds but the batteries lasted a pretty long time. The screwdriver was put back in the garage.
Then this last weekend, my mom arrived with a bunch of toys she’d saved for future grandchildren to play with (MORE HAND ME DOWNS! We are SO BLESSED!) I thought she’d have a few cause-and-effect toys, and maybe some books. Here is what she brought:
This actually isn't even all of it! The non-electronic toys (and a few of the ones that need batteries, too!) had already been moved to his toy bin by the time I got a chance to take the picture!
See all of those toys in the left two bins? Those (plus a bunch that were already out and around the house to distract Nathan from pulling books off of shelves!) all needed batteries. It’s taken a couple days to change most of them out, and since some of them don’t have “off” switches (parents were apparently NOT consulted in the design of those toys! Anytime something shifts in the toy bin, they go off! It’s startling! And loud! And super duper annoying!) I have a feeling I’ll be replacing the batteries AGAIN before I know it.
And that’s why the screwdriver has returned to its proper place: INSIDE the house, right next to the batteries. 
I think it’s a pretty safe bet that we’ll be leaving it there until we don’t have any kids left in the house. (Though by that point, we may very well have hearing aids or other important devices that need batteries, so I guess we should just always keep that thing nearby!)
