Was this some shade or nah?

So my SO Birthday is this month. My in law told me she’s having a Welcoming the same weekend we were supposed to celebrate my husband birthday. I asked her if she could change her date because she still didn’t have her invitations. She said she couldn’t because she had already paid for them and were done. I told her you should have asked me ! Or at least say “hey I’m having a party when is your hubbys birthday so we won’t celebrate it the same weekend. Out of the whole month she decided to make it the last week of March being my hubby birthday. And she has to know cause we celebrate his birthday every year 😒. And after all that she still has the audacity to tell me “don’t be late to the party” like bitchhh 😤
