Tease you

"Hi guys." Kristy said.

"Hi Sis." Said Richard

"Hey." You said awkwardly.

"Your friend look cute." Says Kristy

"Of course he does! He's growing a pair of man boobs too. Says Richard Ouch!" You punched him on his arm before he can continue further.

"Oh my god! Are you kidding me? He's wearing my bra too! I was wearing that bra until I was in high school, one of my favorite. What should I call you?" Kristy asked. You gave her your real name.

"That wouldn't do, you need to give yourself a girl's name. Give yourself one or I'll pick one for you."
