What's in a name?

Yesterday, Bailey had a new girl in his preschool class. When we walked in and he started to take his coat off and spotted her, he immediately gave her the once over, then the stink eye. She immediately stink eyed him back.

Bailey (4): What's your name?
New girl: ...
New girl's mom: Her name is Alison. Or you can also call her Ali.

New girl gives the stink eye to Bailey, Bailey's mom and her own mom.

New girl: I don't have a name.
New girl's mom: Yes, you do.

Bailey (obviously since she had no name, she wouldn't understand his name either): My name is BAI-LEY.

Bailey's mom to new girl's mom: Don't worry, they'll get along just fine.
