Now you can really enjoy that margarita.

Vacations are meant to be relaxing, but sometimes it doesn’t work out that way. For a lot of people, the moment that their minds are finally clear of the day-to-day distractions of work and school and family, their silly brains try to fill the void by worrying that they left the stove on.

According to Lifehacker, there’s an easy fix to resolve the question of whether or not you left the oven on—as you make your way out of the house, step into the kitchen, and snap a photo of your oven on your phone. That way, whenever your brain decides to interrupt your afternoon siesta with a panicked thought about the state of your burners, you can put your mind at ease by simply flipping to the photo of your stove, looking to see that, yes, all the burners and the oven were left in the off position, and then hopefully going back to your nap.

This little trick isn’t just for ovens, either. Snap a photo of your air conditioner, your fireplace, the lock to your back door, the garage, the upstairs windows, or anything that might cause you to wake up in a useless panic in the middle of the night. Once you have photographic proof that you left everything in its proper place, hopefully you can go back to enjoying your vacation.
