My son was uninvited from a party because I didn’t RSVP in time  — it’s disgusting behavior

She’s RSVPeeved.

An irate mom says her son was uninvited to a friend’s birthday party because his attendance was confirmed after the RSVP date had passed.

Sarah, a content creator and mother-of-four, shared the story to TikTok, where she sparked a heated debate about party etiquette.

Sarah said she RSVP’d to the party on her son’s behalf “a couple of weeks later because I’m crap at texting people.”

She was left surprised when she received a text back from the host saying the party had been cancelled.

But the mom subsequently learned this was a lie, telling her TikTok viewers: “All of my child’s friends were texting him saying ‘Why aren’t you at the party, how come you’re not here, we want to see you’ blah blah blah.”

“So the parent lied and said the party was cancelled,” the irate mama fumed. “Like why invite my child to a party if you’re going to pretend it’s not on anymore, I just don’t understand.”

Sarah signed off her clip saying her son was upset and describing the host’s lie as “disgusting behavior.”

However, not all viewers empathized with the fuming mother.

“Should’ve replied sooner,” one unmoved commenter tartly wrote. “People need numbers for bookings.”

“To be honest this is on you,” another chimed in. “It’s infuriating that parents do not respond for weeks… Parties cost a lot of money it takes two seconds to reply. Yes you’re coming or no I can’t come.”

But many TikTok users were more sympathetic to Sarah and her son.

“I would have confronted the said parent,” a supporter stated. “That’s an awful thing to do to a child!”
