My cute little sister is turning 12 and needs to choose what she is going to do for her birthday party. but can't make up her mind! please respond as soon as you can. her birthday is at the end of september. she wants to invite about 20 girls. aging 10 to 14. Some of the girls are sportsy, some are cuteies, and some are inbetween. Thank you if you share some ideas for my little sis!!!!!!
