fifteen @ fiveteen

This morning I heard my cousin was counting number from one until fifteen.

One
Two
Three
Four
Five
Six
Seven
Eight
Nine
Ten
Eleven
Twelve
Thirteen
Fourteen
Fiveteen

Aiyokkk... She said it wrongly. When I corrected her, she won't believe in me. She still want to say it as fiveteen instead of fifteen. Even if her mother corrected her, she still wanted to do or say the way she want. Isk2... Kecik2 lagik dah tunjuk ketegaq. Didn't believe in us, adults.
