Definition: Given a real-life anecdote of a complex ethical situation, generate a suitable title that describes the main event/root cause of the situation. Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: For context: This friend of mine has a thing where people go over to a dollar store, pick out food, and try to make a 3-course meal out of it. 

He normally invites 3 people to his house for this, and we make a fun night out of it. This time, he told me that it would be me, friend 1, and friend 2. I am currently in another state at the time of posting this, and he knows that. He also knows that I would be back in time to attend whatever he had planned. I decided to text him about it to get a time. 

He then said, 

"Oh I thought you were out of state, so I invited friend 3"

I then asked,

"Ok, so am I still coming?", to which i got a stern "no".

This is where I started getting a little pissed. I just politely asked him to ask me before he invites someone else next time. 

He then says,

"You were 4th on the list".

I know this is a lie and at this point i'm trying not to crack, so I ended the conversation. Keep in mind, he had a conversation with me about this event multiple weeks ago in school.

AITA?

getting aggravated at my friend for convincing me I was invited to his house to hang out with a few friends and then saying I can't come last minute
