Is AUTHOR wrong in the post ? POST : I called a group of friends earlier this week and set a plan to hang out on a Friday night. I got the group together, set up a time and venue. I had watch a certain movie that I really enjoyed and wanted the rest of the crew to see it. I specifically mentioned this to them and told them that was the reason I set up the get together. 
On the very day of the hang out, a friend in group suggested we see a different film because he did not really like that one. I was infuriated because his concern was not mentioned earlier in the week. He suggested a second movie and I agreed hesitantly . We get to the theatre and he again changed his mind, saying we could just go home if we didn’t want the new movie he chose. This is what really pissed me off. Take it we are in our early 20s(and this is his second stunt he has pulled in this manner) and I am really trying to learn mature ways of dealing with situations. AITA for being mad?
