My mom turns 60 next month and my siblings and I have been planning a surprise dinner for weeks. We had a group chat with basically everyone involved except her and last night I had it open on my phone while we were figuring out who was bringing what. I went to add my aunt Michelle to the chat. I have absolutely no idea how I managed this, but instead of adding my aunt, I added my mom.

Normally that would be fixable if I noticed immediately. Unfortunately the group chat was literally named OPERATION OLD LADY. Even worse, the messages directly above were my brother asking who was picking up the cake, my dad saying he’d get her out of the house by 5 and me saying just make sure mom suspects absolutely nothing.

I saw her name appear in the members list and immediately tried to remove her but I was too late. She had already read everything ,nobody said anything for about thirty seconds. Then my mom finally sent sounds fun. what time should I pretend to be surprised? My brother started calling me an idiot, my dad sent about six laughing emojis, and my mom has apparently decided she’s still going to act surprised just to make me suffer. So now we’re still having the surprise party, except the only surprise is going to be how convincing my mom’s acting is.

TL;DR: Tried to add my aunt to the group chat planning my mom’s surprise 60th birthday. Added my mom instead. The chat was named OPERATION OLD LADY and she read the entire plan.
