"Okay, okay, let me explain," you say, trying to stay composed as the group chuckles.
You take a deep breath and begin your explanation, hoping that it clears up any misunderstanding. After a few moments, they all fall silent and listen to what you have to say.
As you finish explaining, the group nods their heads as if they understand. They try unsuccessfully to suppress their laughter and smile as you finish talking.
"Well, I guess that explains it!" V says cheerfully, still somewhat amused.
J grins mischievously at you. "You learn something new every day!"
If they noticed something unusual, it's up to you to decide how long you can keep this a secret.
