At this point in history, phone calls are a pretty standard affair. You call someone and someone picks up the call to answer you. Pretty cut and dry.
Sometimes though, calls can be intercepted. Not by spies or government agencies. But by cats. To think we all wasted all our fiction on conceptualising monkey uprisings, not realising that the feline race was gaining on us.
Can't wait for cat call centres though.
"Hello, my TV isn't working."
"Yes. I did try switching it off and on again."
