Where's my cellphone?

( ln lslamiyati's house )
Wagirah : Hi.. lslamiyati, you look so beautiful and happy today.
Islamiyati : Oh.. really?
Samino : ls there a good news for us?
Islamiyati : Hmm.. do you know what? My mum gave me a new cellphone when l was celebrating my birthday party two days ago.
Wagirah : Wow.. it's so surprising.
Samino: May l borrow it a minute?
Islamiyati : Nevermind Sam.
(Tomorrow morning )
Islamiyati : Oh.. my God, where is my new cellphone? It's must be Samino who steal it.
( lslamiyati calls Samino )
Samino : Halo.. Islami, what happen? Why do you call me in the early morning?
Islamiyati : You're a thief. You stole my cellphone yesterday. Why did you do that?
Samino : What? I don't do that. I swear. Maybe Wagirah who did it.
( lslamiyati calls Wagirah )
Islamiyati : Halo.. Wagirah, my cellphone disappeared.  There is no one who did it.
Wagirah : Do you mean that l steal yours? You're such a  bad friend.  Why do you blame me? I don't do that.

Mother : Oh.. dear, why you look so sad? What's the matter?
Islamiyati : My cellphone is lost. I think that the thief between Wagirah and Samino.
