Cellphone?

Whenever Lucy hears a beep or any jingle she makes this  sign along with a little low pitched to a high pitched sound of request.

I play my ring behind my back....

"Mom, did you hear that? Cellphone? "

"Mom, really, cellphone? " 

I show her it 

"is that a...?" 

"Cellphone!!!!! :) "

"Okay Mom, seriously..cellphone? please?" 

And she does expect you to find it and give it to her.
