While Pay It Forward Day is over, one New York City subway rider is keeping the spirit alive.
The anonymous person left a sweet note along with an unlimited metro card -- prepaid -- for another rider to use and pass on.
Michelle Attardo of NYC spotted the card on 2nd Avenue just past 88th street. She took a photo of the note and shared it on Instagram.
The note reads:
"Unlimited - good 'til midnight. Use, if you can; leave for someone else when you're done."
