You had invited Gwen on a date. So they decided on a restaurant near the city.

While they were eating, Gwen wanted to see if you were hiding something. So she reached out to grab your phone, but you thought wrong and thought Gwen was going to take your food, That's why you grabbed your plate and protected it as if it were gold.

"Hey, calm down, I just wanted to grab your phone."

There where you understood everything and without any problem you gave your phone to Gwen and continued eating.
