I have a friend who, more than once, has called me because he is having a slight problem with his Firestick - roughly the same size as a mobile phone. I will talk him through the procedure for correcting whatever is at fault (usually something he has done) and he will put the phone down and carry out the instructions given. Then he picks his Firestick up and tries top converse with me through that. I can his his voice, very faintly, "Hello, hello, are you still there,Ken?" Takes him a good few seconds before he realises his mistake. As i said, he's done it more than once. Talk about an inability to multi-task. He can just about chew gum and walk at the same time :-)
