<human>: Today at work it turned out that I got leave work early, by full 2 hours. YES, the news was as good as it sounded.
So I thought about what should I do with this time. First thing came to mind is that I can go watch Deadpool and the cinema was practically about 100 meters away from where I work. 
To tell you about my excitement, I have not been to a movie that is not Animated (pixar, and dreamworks, etc) since my daughter was born. Which was 8 years ago. Sure I could go to a movie alone or with friends, but it just didn't happen. Twist of luck I suppose.

Oh boy Oh boy. violence and shooting, explosions, the movie experience I'm gonna savor. 

Here is how I TIFU - the ticket that I bought online I selected the time 1:45pm instead of 1245. Must have clicked it when walking like crazy. The attendant pointed me to the right cinema room, but did not check time. So I walked into the room where the movie was already playing and was near the end. (Dont wat to spoil by telling up to where but just before the finale). I thinking this movie is awesome with all the action scenes, until the credit started rolling I realized that this is not the beginning its the end and the fact that TIFU

Can you condense the text into a few key points?
