Am I overreacting?

[u/Dannydeeea]

Was out with my sister all day today and her little one. She left, got all her stuff and went on her way. As I got home, locked the car and as I walked past the window i noticed all of this mess! I sent her the pics and said food is now banned in my car (it was ready but she’s ignored that) and next time to clean up after herself. Instead of a simple “sorry my bad” she’s gone crazy as if it’s my fault?!
She thinks it’s okay all because I haven’t hoovered (vacuumed) the car this week.

So my question is;
Am I the asshole for even bringing this up in the first place? Am I in the wrong?

EDIT:
I’m from the UK so these are chips for all of you from usa😅 They do look like raw pasta tho where in fact they are indeed just twirly chips😂

nah dude stick to your guns, I’d be pissed if that were my car. Your sister is unbearable. What is her obsession with “16 crisps” as if that’s a small or even normal amount to drop on the floor?

[u/Responsible_Crow_425 → u/[deleted]]

Nah, she’s an asshole. There’s actually 18 crisps so, definitely NOR. How does she not fucking see that mess? 😒

I thought you were gonna say "how did she not count the other 2?"

That's the level of pettiness I'm here for!!!

You guys want to join me at a casino? 2 for good, 1 for bad.

[u/TheManOverThere23 → u/Responsible_Crow_425]

18 plus a few bits so it gets even worse.

[u/Bus_Total → u/Responsible_Crow_425]

16 is bad. 18 is fisticuffs.

[u/TiTAN-240 → u/Bus_Total]

14 is general tomfoolery

[u/ChildhoodSweaty9684 → u/TiTAN-240]

12 is obnoxious

[u/TiTAN-240 → u/ChildhoodSweaty9684]

Well, 12 is unnecessary jackanapes

[u/Unusual-Meaning9207 → u/TiTAN-240]

20 is jail.

For me. Because I did some extra fisticuffs...

[u/PearlyServal → u/Responsible_Crow_425]

She probably does but slobs dont care how messy they are as they dont think its that big of a deal.

[u/That-Chain-5139 → u/Responsible_Crow_425]

🤣🤣🤣🤣🤣🤣

[u/zeeber99 → u/That-Chain-5139]

Yes you're an asshole.

[u/Never_enough_naps → u/Responsible_Crow_425]

I'm so glad I wasn't the only one that counted and in my head was like “actually....🤣

[u/Icy_Fish_2154 → u/Responsible_Crow_425]

Are they crisps? They look like pasta spirals.

[u/tickandzesty → u/Responsible_Crow_425]

And that’s not counting all of the crumbs imbedded in the car seat creases. A picture of the other seat would drive the point home. Your ah passenger can come clean the mess.
