TIFU by eating my sister’s labelled yoghurt

She bought a pack of four last night and labelled it with her name on it to signal to the rest of the family “hey don’t eat this, this is mine”

In my defence I did not see the whiteboard-pen labelling when I took one from the fridge and ate it. Also I was really hungry.

Furthermore, two packets were already missing so clearly the rest of my family were also assholes

Anyways, she came back home from work and opened the fridge door and immediately stormed upstairs to me and my brothers room and shouted “WHO DID IT.”

“I only ate one.” My brother said.

“Same here.” I said

“WHEN YOU SEE MY NAME ON THE PACKAGE DONT FUCKING EAT IT!”

Then she went into her room and slammed the door loudly.

My parents came running a few seconds later trying to compromise: “we can buy you more tomorrow…” but she didn’t answer.

I feel really bad about the whole situation. First, when I ate the yoghurt she was probably craving after her long shift, and second, after I lied about only eating one, when I actually ate two.

Tl;dr I accidentally ate two of my sister’s prized yoghurt and then sort of lied to cover up my mistake
