You text your friend Carl while sending a picture of yourself to him.
"See this hot girl? She needs to hideout with you for a few days. She will explain everything when she gets there". You text. You got to admit, you were pretty cute. But just thinking about Carl made you feel all warm and fuzzy for some reason....
Carl texted back,"Um, ok? I'll believe you "when" she gets here". Obviously, he is not convinced, but seeing is believing.
