Okay. Let's talk specifics.

I log in to an end-to-end encrypted chat with a family member. We talk about life and the subject drifts to plane tickets we already bought for next month and how the neighbor across the street isn't going to be home until the end of this month.

The thief who stole my laptop now has also stolen a recorded conversation along with my passwords. Now they know when two houses will be empty. This would not have happened without pictures of my screen being taken frequently.
