While many couples are faithful to one another, there are many who cheat. Partners have discovered infidelity everywhere from doorbell cameras to selfies even in restaurant reviews and on Google Maps. Well, it turns out that there is a simple trick that can show you if your partner is stepping out on you, and all you need for it is a certain type of mirror.
A TikTok user shared the hack in a video, explaining that you just need to use the mirror in the sun visor in your partner's car. Many of those mirrors have a sliding protector over them, and to do the trick, all you need to do is leave that slider half-open. If the next time you get in the car that slider is either fully opened or closed, you know someone else has been using it, and odds are good your partner may be cheating.
