Input: Text: so about a year ago i separated from my partner. i now live alone with my two kids. when packing my stuff and moving out i had inadvertently packed a bag of her underwear in with my stuff. i didn't realize this until after the following had occurred.

unbeknownst to me, my youngest boy who is 3 has decided to rummage through my wardrobe and has gone through a box of crap i still haven't sorted and has found a bag of my ex partners underwear. he proceeds to take a pink g-string into the en-suit of the spare bedroom and left them there.

whilst i was cleaning up the mess he made i find the bag of my ex's underwear. a few things go through my mind and then i figure shit, i can't give them back now. that would be way to awkward. so i just throw them out.

so a few days later i go to give my boys a bath in the en-suit of the spare room as it has a huge big bath they love to play in, and i spot a pink g-string on the floor. i figure it must be from my brothers partner, from when they were here a week or so ago. so i just kick them into the corner and figure when they come back in a few days they will find it and realize they must have left it here.

nope.

so now they are here with their kids and have started to unpack. my brother goes into the bathroom and sees the g-string. i'm on my computer in the room right next to them and i could hear them talking. once they figure out that the g-string isn't hers as the size is not her size they go silent. i realize at this time that it is my ex's g-string, and where it came from.

my brother then walks in to my room and asks with a huge smirk on his face:

"these yours bold_claim?"

i let out a nervous chuckle and try to tell him no, it's my ex's.

of course he doesn't believe me.

i take a brief moment to realize that no matter what i say i can't get out of this without it looking like i had tried to keep some of my ex's underwear for nefarious purposes.

i explain to him that i had found a bag of my ex's underwear in my unpacked box of stuff but this only reinforces the conclusion he has already come to of me and said shenanigans.

he walks back into the room and nonchalantly proclaims to his fiancee "yep, its bold_claim's"

so now my brother and his partner genuinely believe i have been up to no good with my ex's underwear.
