Random conversations with the boy

So I'm at work and I phone home - more to check that his daddy has actually remembered to pick him from his aunts more than anything.
"Hello buddy."
"Hello Mummy. I'm on the computer, on Cbeebies. Brum is on."
"Great Joseph, sure you can tell me all about it when I get home."
"No mummy, hang on. I'll just put you on speaker phone."

Speaker phone??? He's four!
