I was reading a great book in my favorite chair when suddenly the light went out. I flicked the switch on my reading lamp, but it did me no good. It looked like that light bulb had burned out. I went to the hall closet and poked around, and luckily I found just what I needed, a package of light bulbs just like the one that had burned out. I brought one of the new bulbs back to the living room, and unscrewed the old used-up light bulb. I put it on the kitchen counter so I would see it in the morning and remember to recycle it at our city's transfer station. Then I screwed the new light bulb into the light socket  and turned on the lamp. The light shone bright and clear. I settled back into my chair with a sigh, and opened my book again. 
Question: How long did it take to remove the old bulb from the socket?
Few seconds
