Five year old Savannah goes to her mum and starts to talk about hairdressers: 

“What was your hair like at that time?” (Savannah)

“What do you mean ‘at that time’?” (Mum)

“When you were a child, of course!” (Savannah)

Her mum explains, “Listen, Savannah, hairdressers have existed for a long time.  We had them even when I was small.”

Savannah replies, “Really?  But you were born in Jesus’ time.  Are you sure they had hairdressers in Jesus’ time?  I don’t think you can remember.  It’s too long ago.  You must be mistaken.  They didn’t exist!”
