Is AUTHOR wrong in the post ? POST : Last five minutes before I leave work I have the urge to do happy hour. As I'm leaving I see my coworker (friend more or less) and I ask her if shed like to join my friend and I. I am aware she has a child whom I've met before. Nice kid as far as they go. I also know she gets one day out of the week to herself. Hoping its today I invite her to happy hour with my friend. 

She says maybe and she'll get back to me soon.

Fast forward. I arrive at the local brewery and receive a text. "I'll come but I have "child" with me. Grab a table." 

At this point I'm a little annoyed as I invited her and not her and her son. Granted if it was just me I would have grabbed a table for us. 

I text her back and admitted that I didnt know she would have her child and that my friend would be opposed to sitting at a table. Knowing my friend, I know he would be against it. Because who would want to have a beer with a child after a long day of work. AITA?
