It’s more than a few years ago, when PCs are new, parts are expensive and this pilot fish is working as a PC tech for a school district.
“One day, I was called to fix a PC at a school library,” fish says. “After I fixed the PC, I noticed the keyboard was incredibly grimy due to many little fingers typing on it.
“I snapped the keys out, shook out crumbs and dust, cleaned each key and reassembled the keyboard.”
Next day, fish gets another call from the same school library. One of the library admins is complaining that her computer shows garbage on the screen when she types.
After asking a few questions, fish concludes that the PC has either a virus or a bad motherboard. He grabs a replacement PC and heads back to the school.
