They forgot:

-Bic lighters -Punch buggy lawnmowers everywhere -Ice cream van jingles zigzagging off in the distance like Jaws creeping up on your neighborhood -Hoopties zigzagging off in the distance with deep bass at night like Will Smith and DJ Jazzy Jeff creeping up on your neighborhood -Nintendo Zapper clicks -The smooth sounds of classroom movie projectors clattering in the dark and putting everyone to sleep -The gentle “booop” of automatic classroom informational slideshows before every slide change -Actual groaning, neighborhood-wide fire alarm that woke you up out of a deep sleep thinking it was nuclear war
