This reminds me of the time in HS when a letter broke off my laptop keyboard and my parents insisted on taking it to the shop for a repair. Turns out they really just wanted the shop to turn over my search history and chat logs. I already knew my parents were nosy so I would always delete it anyway.

One day I came home from school and they said the shop fixed the keyboard but just needed my password to test it and do updates. I said no it's fine if he can type in anything into the password then obviously the keyboard works, and I already did the updates regularly.

They literally had to beg me for the password and they were like pleasssse just give the shop the password so they can finish their checklist and you can get your computer back, and I was like fine if it's the only way I'm getting it back. Of course nothing came of it because there was nothing to discover.

Then my parents got the computer back but kept it in the trunk of their car for a week, and I accidentally saw it when we were leaving Old Navy which started a whole "I don't believe this!" discourse in the mall parking lot.

Moral of the story just talk to your kids instead of spying and lying, because they know and it won't work!
