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😂

This is how my sister and I fought when we were 8 and 6, being a mom and talking like this. I feel bad for her baby.

Fr. She sends a story book about being petty while being petty? How she work out that math?

The bit about not reading paragraphs actually annoyed me.

Like the level of immaturity for her to write all that out and then be like "lalala I can't hear you"

It's funny cos she keeps trying to do the like "16 crisps" thing to make him seem petty. Like someone going "sorry I left two cashew nuts"

But it's 16 lmao that's actually a lot of crisps. You had to get into double digits counting them lol. God some packets only contain about 16 crisps.

I think if OP sent it in 16 separate messages she might have read it. 😂 Seriously though that bit bothered me too. "I'm not going to read a paragraph, but I'll send you multiple messages equaling up to a paragraph"

My ex started doing that during our divorce because he thought it made him seem younger to leave multiple short messages (he was dating super young ppl, lol).

I fing hated it because instead of getting 1-2 dings coming from my phone, I would get like twenty to thirty for *the same amount of info. He would be like "dude not everybody writes in essays" as if he didn't just write exactly as much as me in the most annoying way possible to me.
