Happy stupid Birthday!

It's my brother's 20th birthday today and I'm still trying to decide if I want to observe this day. I love birthday's and making them special but he is making it hard today. I was all excited yesterday and I stopped at Target and returned a shirt so I would have enough money to buy him something. I was just going to get a gift card and then write in his card "I want to give you something else and I will surprise you with it next week!" or something clever like that. However, I found this thing for your car and its really hard to describe without seeing it so I won't even try. I thought I would get him it as kind of a joke but he could totally return it, no strings attached. I also got some crete paper so I could decorate his car in the morning so when he goes to leave for work he would be surprised. All excited, I drove towards home with my purchases. I got home after him and he emerged from his cave downstairs and greeted me with a grunt.
Me: Happy Birthday Eve!
Brother: (no response)
Me: Do you feel any older?
Brother: (still no response)
Me: Are you going to answer me?
Brother: Stop! You are being a hoody doody!

After our short conversation, I decided all birthday plans were to stop! I got up and walked away...GRRR to brothers. He got in the shower and I looked outside and noticed it had started to rain pretty hard. I then saw that his drivers side window was down. I had 2 options: 1. Go tell him why he is in the shower and ask where his keys are so I could go close his window. or 2. Just sit and watch as the car slowly filled up with water. I know I will be paying for it later but I choose option 2. It was actually pretty funny to hear him get out of the shower, walk to the living room and see his car sitting in a downpour with the window down. I heard him rush out the door. I knew my karma would go down, but it was still funny. Hopefully he will be in a better mood today. I should remind him he isn't a teenager anymore, sine he turned 20 today, and he should suck it up and act more like an adult! I'm sure that will help the situation.
