A Broken Nipple

I was puzzled at why one of the keys on my keyboard seemed to have sunk in. Worst of all, it was my spacebar. After lifting the key from the keyboard, everything appeared to be in order. I could not discern any missing parts and such. It was only upon close examination that I found that the silicone nipple under the spacebar had broken and thus lost a significant bit of elasticity. I then set about thinking about how I could get a replacement. It seemed terrible to send the keyboard in for servicing: It'd take days at least. Sending it to the shop seemed a poor choice, since it would only cost me a sum to service. After teetering at the brink of deciding to buy myself a new keyboard, I realized that I could simply replace the nipple with another one from one of the keys. But which one? A quick mental check revealed the most likely candidate: The scroll lock key. I prised it from the keyboard and did the swap. Thanks to you, scroll lock, I am able to type this today. Your sacrifice was not in vain.
