Detailed Instructions: Given a post that is a real-life anecdote of a complex ethical situation and a question asks if AUTHOR, NOBODY, EVERYBODY, or OTHER is wrong in the situation. Answer the question and classify your answers into yes or no.
Q: Is OTHER wrong in the post ? POST : First of all english isn't my first language so sorry in advance for bad grammar.

The story goes like this. One of my best friends and I bought tickets for one of the biggests festivals in our country a month ago. They cost 150€ more or less, it's a five day festival and the place is pretty far from where we live, so for us planning all this was a big deal. 

Now fast forward to now, I just discovered that he's been planning behind my back a trip to India with other friends. This wouldn't be a problem at all if it wasn't because he has to cancell our festival plans. 

This has really hurt me, not only because he just ditched me for other friends and now I have to resell my ticket, but because he hasn't told me anything and I found this out thanks to other friend. 

All my friends say I shouldn't be mad,that i shouldn't take it as something personal, that I should understand that a trip to India is a unique opportunity and that I'm overreacting. I just feel like abandoning a friend after buying and planning everything is a dick move, even if the other plan is the best plan in the world. AITA?
