We are plagued by cold callers, despite having our number on the tps database. I went through a phase of getting annoyed with them but have realised it's just a job for these people, can't be mean now. Tried ignoring the phone, but soon enough ds, 3, figured out he could answer the phone.
He's a lovely, chatty boy and takes great care to explain in the tiniest detail what he's doing. They always hang up on him and the poor boy is left very confused, asking "hello? Hello?" down the phone. He's probably the nicest person they'll speak to all day so why hang up? He always gives me the phone.... Eventually!
