i take it as a sign that summer is approaching when my windshield is covered with what would have been pesky bugs leaving yellow and green markings. too much detail? sorry.
a lot of the times, i don't even bother in trying to remove the substance by helplessly wasting my washer fluid on those pests. instead, i like to wonder what kind of insects they were...as i don't recall ever really encountering many yellow or green flying insects. any ideas?
