Well, years of experience has taught me that begging doesn't work. You're just going to make her more frustrated and push her further away from the decision you want her to make. Calmly sit down and talk to her about what you'd like to have and maybe make a deal with her. If she sees you're being responsible, doing your homework/chores, or whatever, maybe then she'll get you one. Don't make empty promises about what you're going to do though! Maybe you can agree to do chores in the house. That way, you can make a bit of your own money, and then spend it the way you choose. That's how I got my first Tamagotchi 12 years ago...had a bit of my money saved up, and just happened to see a P2 Tamagotchi at the toy store I visited. Don't worry, things just work out.
