Input: Text: this happened when i was 5 or 6. i'm 18 now, but i just discovered reddit, so here it goes.

my parents had allowed me to sleep over at my grandparent's and that obviously meant plenty of food and plenty of fun, thus 5 year old me was on cloud nine. 

it was probably after lunch when i decided i was going to go outside and play on the balcony. i used to have this blue toy car that i absolutely loved, so i immediately picked it up and started playing.

i can't remember what exactly was going through my head at that moment, but, at one point, i decided to stick my toy car in a drain pipe, probably just to see if it would fit. then, i just left it there as i headed to the kitchen to grab some ice cream and promptly forgot about it ever existing.

now, you have to understand that in my country (greece) the sewer piping is quite outdated and prone to blockages. there are even warnings in public restrooms about flushing paper down the drain as even that could block the whole sewer system. naturally, i didn't give a fuck.

long story short, the toy car made its way down the drain pipe and into the sewers in just a couple of hours without me having a clue. it blocked half of the neighborhood's sewer system and, as a result, anyone who lived or worked in the basements and on the ground level floors of pretty much every building on the block was in for a nasty surprise the day after. a brown, smelly and full of shit surprise. 

somehow, i managed to keep my cool and nobody found out it was me who caused around €150,000 in damages. except my parents, of course. as soon as word got out that a blue toy car had caused all of this, they knew it was me who did it. obviously, they were furious at me, but they never ratted me out, though and just left the whole thing be. thank god everyone involved had flood insurance and we didn't see any lawsuits coming our way. 

i haven't admitted any of this to anyone, but my parents, even to this day.

TIFU by blocking part of the sewer system and flooding half the block.
