Sinead is a head head that rages a lot. She doesn’t care what people think about her so is sometimes a bitch. People try make her feel better by saying she is hot but she really is not. She is good at picking up musical instruments and is good at sport. Is offen called sinhead. Have lots of friends and they all love her because she is so kind and cares for them especially when they are sad.
GIRL 1: wow Sinead just had a fat rage at me.

GIRL 2: it’s ok she is ranga.

GIRL 1: yea that’s right a fat ugly ranga.
SINEAD: hahahaha I know aye.
GIRLS 1&2: I forgive you Sinead your my best friend.
