Male caller claimed to be involved with children's charity, not asking for a donation or doing a survey; just wanted to ask two questions. Those were how I rated, on a scale of 1 to 10, support for disabled children, and then the same for children with cancerous tumours. After getting answers to those questions, he asked if I currently supported such charities. Then he had a stab at guessing my age from the sound of my voice. Definitely time for a goodbye.
