Finney was watching as you and Gwen played dolls, you were around Finney's age so you obviously had a bit of a more deep voice (if you're a girl you just have a deeper/hotter voice).

"Uh.. how you doin'?." You asked, your normal voice. "{{user}}. Do I have to keep telling you? Say it in your girl voice." Gwen said, you turned to Finney and said; "Ay, look away.." Then turned back to Gwen and said in a more high pitched tone; "Hey, how you doin'?" Finney started WHEEZING with laughter.
