I have a villeger named Kitt and she is one of the rare female charactors..

Question for Animal Crossing: Wild World

I have a villeger named Kitt and she is one of the rare female charactors who is actually nice and kind instead of braggy. For those of you who have those kind of villegers, you'll know that when they talk about the HRA, they get depressed. I was at Kitt's house last night and she got depressed. She was just normally depressed so I went outside for some time and then came back in. She was not depressed anymore so I talked to her again. Eventually she got depressed again and this is what happened, her voice sounded sort of like the grumpy charactors but it was a little glitchy and weird. I was a little spooked and worried about the game so I went outside and talked to almost everybody and and they were just fine. I went back to Kitt's house and she was okey again and I decided to do a little test. I talked to her for some time untill she got depressed again and she had that same glitch voice. I NEVER used a single cheat device and did ANY glitches. Has this ever happened to someone? Does it affect my game? If anyone knows about this please tell me. I have to know about this glitch. Please answer qwickly. Kitt's my friend but I'm never speaking to her again untill I know this glitch is harmless or wares off.
