Meta this didn't happen today but about 8 years ago.

So, it's a hot summer day in Canada (a nice 50), and as a nieve 8 year old, I thought it would be fun to do a lemoaid stand to afford more Pokémon cards.

Now, my sister is 7 years older than I, and she (as the typical depressed emo 15 year old) couldn't give less of a shit. She was out in the backyard

We didn't live on too busy of street, maybe sold a few glasses but the pitcher was still about 1/4th full. I was getting bored so I decide to go pour the glass in the backyard to make it look like I sold all of it to make my parents proud of me for once. I went to pour it down a hill, this went down to a small little forest / pond area where my sister apparently was, so as I poured it down the Huss it apparenty reached her, she looked up at me absolutely mortified.

Now 8 years later, and we can't go a family dinner without talking about how I pissed on my sister.
<bot>: had lemoaid stand, didnt sell it all, to make myself look better I poured it down a hill, right upon my sisters head.
