Help me understand if i was rude or SIL was out of line.
Some background info:
We host Easter party since many years (same as Christmas and other parties) and we are happy to do so
SIL's family is way wealthier than us
SIL and her DH are absolutely not generous
On Easter day, i was in the kitchen prepping food and SIL's DH asked if he could store their meat in our fridge.
It happened already in the past that SIL brought some meat specific for them at our grill parties so i did not think so much about it.
When we started to grill I told my DH which one was SIL's meat and I made sure their meat finished on their tray.
At the end of the party, she opened the fridge and saw that their meat was not there anymore and she asked where it was. I explained her that i thought it was the meat they wanted to eat at the party and she was very pissed off.
She said that it was their meat, that they wanted to eat the day after, it was not to be shared, and i had to right to use it without asking.
I apologized, it was clearly a misunderstanding, and she went on saying that i threw off her plans etc.
I did not know what to say, so i apologized again and told her she could take something out of our fridge to cover for tomorrow.
She then took all the meat she found (which was supposed to cover our family of 4 for the week) and said again that she found very rude that i used their meat instead of the one i had in the fridge. (Which i actually DID use. I just did not use the food i bought for the normal week)
I was then distracted by my toddler trying to climb on the table and by the time i was back she had left with her family.
So, she thinks i was very rude, and i think she was super rude.
What do you think?
