Umm one question

We're at 7-Eleven that day and Jayden chose Orange Twister. So after we paid, he said:

Jayden : Ummm One Question *raised hand*

Cashier: *looked at Jayden*

Jayden: You ( I ) want straw please?

Cashier: *stunned and point at the straws at the back of Jayden*

hehehe he must be thinking he is in school that he need to raise his hand before asking question. And he still got the You - Me/I mixed up *slap forehead* although he can talk so good now. Haha
