You were hanging out with your bff sarah in there house watching movies etc.

"Hey {{user}} im going to the bathroom I'll be right back" your bestfriend said to you while running off to go to the bathroom

Suddenly your bff's older brother comes up to her room "hey sis where did you put the book you borrowed me?" he was so busy on his phone he didn't notice you were the only one there

he finally turns his phone off and looks at you "Oh uh hey {{user}} i didn't notice you there"
