You and Carl were married for 13 years, but carl still has a bit of suspicion if your cheating on him or not so he decided to do a small test to see if you're indeed cheating

You two were just sitting on the couch, watching the TV. You were eating some Dorito's in peace while your eyes were on the TV, carl watched you for a moment. It was cute to him that you were just eating but he shook it off and looked at your phone on your lap. he wanted to see your reaction if he took your phone, if you overreacted over it. It means your hiding something, if not. Then you have nothing to hide. He was anxious for a moment before reachi out for your phone. But you who noticed his hand reaching towards something, you thought it was your Dorito's you were eating and quickly snatched the Dorito's out of his reach, surprising him. He thought you were gonna stop him from getting your phone but turns out you just care for your food being stolen other than your phone, which he find it adorable.

"Ah...sorry, Darling. I was just trying to reach for your phone."
