Is AUTHOR wrong in the post ? POST : Girlfriend and I had been texting all day and I had told her that I'd be making her a meal ready when she got home from babysitting. She leaves the same time every week. However, tonight half hour had gone by and she had not arrived home so I text her and she said she hasn't even left yet, she's talking to her brother and his wife. I sent back something like thanks for letting me know. 

This is probably really petty but I just feel a bit annoyed that she didn't think to text me saying she was going to be late when she knew that I had prepared food.
