Whoever you do in the next 7-10 years, do it well.
Happy birthday..
You for got what teenagers do in this time.
To the OP: Happy birthday! Now that you are thirteen, you are too old to hang out with elementary kids, yet too young to hang out with high schoolers!! Thus you are stuck with the socially awkward middle schoolers! Now that your body is changing, you voice will waver between squeeky, annoying, and downright hilarious! But bear with it, as it marks the coming of hair in all the itchy places and the scents of in-adequate hygiene in order to attract a potential mate! Remember, everyone hates an arrogant eighth grader, so be gracious, courteous and polite so you can get money from rich, old people who pity you and your puberty! Another important thing: never date until you can drive (legally!)(or at least are in high school) , it cuts down on the embarrassment on dates.
In summary, middle school may suck, but hey, there are thousands of other guys suffering through it too (they all just seem to hide it better) along with girls who are having to deal with that "special time of the month" that helps mold them into the ack they are when they grow up.
Happy birthday,
Enker
P.S. December 11 is my mom's birthday too, she is going to be older...(yes older is her age!)
