Today’s first glitch:
A possessive requires an apostrophe: phone’s, not phones. Even if there were more than one phone involved, you’d write phones’, with an apostrophe after the s.
You decide to use your phone’s new app to record sound while you’re asleep. What does it hear?
(WTF, WordPress spell check? Now you’re saying hear is wrong and should be replaced with here in the second sentence? This is why we can’t have nice things…)
