First, let the person you love know when you’ve seen the first lightning bug of the year. Alert her so you may have the chance to charm her and watch as it lifts off your arm while you are grilling dinner.

 
Second, let the sun go down. 
 
Third, call her over when you test the new lights you strung against the white fence. Colors chase bulb to bulb, an order of operations fit to woo the first lightning bug, who returns with this summer’s reawakening flash.
