Last night I opened a bottle of Coke while sitting at my desk. Unfortunately someone had shaken the bottle vigorously before I picked it up. As a result I have lost the ability to type commas on my laptop keyboard. This is not as bad as it sounds. Last night I thought I would have to do without m's n's and spaces. An unacceptable turn of events.
Also for some reason the page down button had developed the capability to initiate a search function within the Firefox browser.
I asked my computer repair-savvy friends how to fix the problem and they recommended that I put the keyboard in the dishwasher and then let it dry for a week. These are the kind of people who grow moustaches for fun and are therefore not to be trusted.
