Copycat

I'm a complete dunce when it comes to modern technology (apart from cameras where I am a whizz).  So I copy my brother who knows about these things.  His Chrismas presents included an Alexa Echo.  So I quizzed him about it and ordered one in Amazon's Boxing Day sale.  It's just arrived, so all I have to do is learn how to use it.  "Alexa, how do I switch you on?"
