Hey bud, if you wanna have a party with guys and gurls, and ur mom is gunna be there, first, you want to make it so she can't be watching you all the time, so she doesnt have an excuse to be watching you, so try and have it outside. If there is a park, or if you have a big enough yard, have a dance party out side. Put on some good music. Start the party lata on at night, so it can last til it's dark, then u have more freedom. Have it start at about, 6:00pm ish, and provide dinna. Have chairs and stuff for people to sit on when they are tired of dancing, and provied lots of snax. Have the party end at 10:30 ish, but dont worry, ther is always room to stay a lil longa. Enjoy!
