Asking Eric: She shows up late and then teases me for being uptight about time

Dear Eric: My friend was recently diagnosed with ADHD. She is now continually late for events or doesn’t show up at all.

On one occasion my friend was supposed to comed for dinner at my house. An hour before she was due, I got a text from another friend saying they were now having dinner at her place. My first friend didn’t contact me at all, not to apologize, nothing. I’d spent a lot of money on food and was cross.

Other times she forgets to show up at all unless I remind her several times in the lead up...
