Am I crazy or what???

I am going with my friend this afternoon to see Marley & Me. I have heard all the reviews and I know how it ends, and I have been known to tear up at a commercial, my dog is 12 years old AND I know the pain of watching your beloved animal being put to (eternal) sleep, so why am I going? I certainly can't be THAT desperate to get out of the house, can I? I don't know, but I'm going anyway. Popcornless with a smuggled bottle of water in my bag. At least the tickets are free.
