road toad

on my way to Lia's house tonight, i was driving on a very dark road through corn fields, on the back way from Northampton to Amherst. all of the sudden i see something small and hoppy and brown jump across the road and it was too late to stop. i am really worried that i squished this frog because i already have horrible frog karma and now i can't fall asleep and am anxious imagining frog guts on my tires and little frogs waiting for their mom to come home & her never coming. (is that real? are little frogs just tadpoles? is there an adolescent stage between tadpole & adult frog?) i guess frogs have good reflexes, and it might have pulled a frogger.
