Sign of the times?

Zeb had his first trip to the eye doctor today.
The doctor asked him if he wanted to use numbers, letters or pictures. First Zeb went for the letters, but then he quickly changed it to pictures when he didn't know the first one. The doctor asked him if he knew what each picture was. There was a heart, house, circle, telephone, etc... When he got to the telephone picture, the doctor commented to me about how funny it is that kids actually know what that is considering how much more common cell phones are.

So, the next time Zeb came across a telephone symbol he called it a cell phone.
The doctor said "Well your ears are definitely working."
Everything went well. He has near perfect in one eye and better than perfect in the other.
