Parents: If you did not already know, a popular thing that Young People of the World Wide Web like to do is replace your sentimental photos around the house with less-than-sentimental photos.
And place bets on how long it will take you to notice. Yes, they are trolling you in your own home.
In January, 18-year-old Kyle Roberts did the same. He told BuzzFeed News he was inspired after he noticed an empty picture frame sitting on a mantle, so he quietly inserted a photo of Guy Fieri holding a hot dog in it.
"Our house is littered with pictures on shelves and the walls," Roberts said, which may be way an empty frame would go unnoticed.
"I printed out the weirdest picture I could think of, while making sure it wouldn't be too obvious, and at that time it was the picture of Guy Fieri holding the giant hotdog."
He then shared it to Twitter as a meme, with the popular caption, "How long until my parents notice," not thinking anything of it.
