Hey! If your 13 year old boy or girl, is planing to have a party, a good idea is what my mom did for me! she had a surprise party for me!! I sent out my invitations it was dated for Sunday, but instead after the invitations were sent out, my mom called everyone's house and gave them the details!! After shopping at Yorkdale for over 2 hours on Saturday I got home and volia! they were all there! I think it was the best birthday party I have every had, and I think everyone's dream is to have a surprise party!! you should have seen how many times I had asked my mom "please ma? come on I'll pretend I never knew about it" and my friends were the best to, cause the didn't even give me a clue about the whole thing, even though they said the gave me a lot of hints and I didn't follow along cause I'm blonde! ya right! but this is 1 party I'll never forget, and neither one of my friends will either!! thanks mom!!!!!!!!!
