I appreciate your thoughts. You can make a dish which you like & mom will permit you as well. You clean your room cupboard, cloths, books, bed, and every thing & change the setting of your room in such away that give a surprise to everybody.
Invite your friends. Make a questionnaire from general knowledge, from nature, from your school books and ask your friends. Who give the correct answer give some gift to her like chocolate, pencil, pen, flower etc.
