Input: Text: smokers can relate, sometimes you accidentally pocket a lighter that you borrowed from a friend. usually it's not a big deal because lighters come and go. 

a few weeks back i pocketed a lighter from a friend who was insistent that he wanted it back. i carried it around with me on the chance that we'd hang out together soon. 

this morning i stood on top of a grate and went to light my cigarette with my friend's lighter because i misplaced mine earlier and plop, down it goes 3 feet, into mucky snow water. 

i shrug it off because it's just a lighter, right? 

i text my friend "rip, lighter". 

he texts back "that was the last trinket i had from mary before she passed..." 

my initial text "rip" made me cringe real bad, and now i feel like a major asshole.
