The other day my dear sweet talkative sister calls me while I'm at work. I answer the phone and she immediately launches into a terribly funny and amusing story about an incident with my niece. I lean on to my desk and - the phone cord falls out of the headset.
I scramble for it, drop it, scramble again, bump my head on my desk and finally, after a couple of frantic minutes, get it reinserted.
She's still talking.
Summer has been conversing with a dead line for a good 60 seconds or more - and she didn't even notice.
