We all have one of those awkward moments in life where you decide to be honest.
The good news is that us girls have hair to cover up our awkward situations!
Teacher: Who didn't do their homework?
Me: *raises hand and looks around. I awkwardly grab my hair and pretend to be actually playing around with my own hair because everyone else did their homework*
Teacher: Look what the cat brought in today. Mary! May you please explain why you did not complete your homework. You seemed to have your hand raised.
Me: *awkwardly laughs* W-what? Me? Nah. I was playing with my hair.
Teacher: Oh, okay. . . .
That is how it is done ladies! ;)
