Input: Text: this happened about a year ago now and i know i'm a terrible person. full disclosure. 

back in late may my cousin was having a garage sale to get rid of some unnecessary stuff before they moved, so the wife and i attended like any good family member would do. wife saw a really nice change table that would look fantastic in my son's nursery! they gave us a really great deal and helped us pack it away into the back of my truck. fantastic.

we got it home and set it up, it worked perfectly with the design of my little dude's room, we were so ecstatic! now, fast forward a few months! we've been using the change table for a few months now, no problem at all. one day, my kid decides he wants to have diarrhea and i have to clean the whole top of this thing. i clean the wood and remove the change table mattress pad and underneath is a small set of hand prints ranging from 1-3 months. by this time, my kid is 6 months old and we had the exact same set, so i thought it was ours and i threw them in the tin with the rest of the hand prints. we take these out regularly to shuffle around and compare how big he's become!

moving on, my cousin messages me a bit panicked saying he left his set of his child's handprints underneath the damn change table mattress pad for keepsake because he was planning on getting a tattoo of his kid's hand on his damn chest. that's not okay. why would you leave them there??!?

so i'm shuffling through trying to figure out which prints are his and which are mine and it's nearly impossible to figure it out as they look the exact same. so i guess. i send him off what i believed to be his.

a little while later he posts about his new tattoo of baby's hand over his heart. aww cute. i wanted to do something similar! so i pull out the handprint container and pull out the prints of my kid's hand. i'm shuffling through and i notice some have dates on the back to correspond with the "1 month/ 3 month/ etc" timestamps. ....... i look closely and i see a few from this set don't match up with how old my kid is. i sent my cousin the wrong prints. he has my kid's hand tattooed on him. i f'd up. i didn't mean to. i still haven't told him or asked my prints back. what do i do? james bond it?!

TIFU By letting my cousin get a tattoo of my son's hand.....
