"i was at breakfast when i saw this hummingbird, and hummingbird was having breakfast as well... and i don't know if you know but hummingbirds are supposedly good luck and i was just thinking about hummingbirds. i was thinking 'how fast does their heart beat?' , like 'how many beats per minute?' and using that idea as an idea for someone making you feel, instead of those butterflies, making your heart beat really, really fast."
