Donna wasn't some naive teen, she had taken physics and chemistry classes as part of her associate of science degree requirements. She knew that organisms can't change in the ways the program was claiming, therefore she knew that this had to be some kind of prank. Given that someone spent money to send it to Alex in the mail and that someone programmed an elaborate looking program, even if it didn't function, it was probably going to say or do something mean once activated, expecting Alex to be the user.
Being a good and loving sister, Donna insisted on looking at the program first. She turned off the Internet connection in case it was a virus and began looking into the settings it offered. Her expectations were confirmed when she got to all the pervy settings, clearly it was designed by teenagers. In reviewing Alex's stats she found the mean insults. The programmer was saying he was gay and had a furry fetish. Donna reversed those and clicked save before Alex noticed, sparing him the offence.
Alex hadn't come out yet and now he never will.
Donna expected the correction to trigger whatever malicious message the programmer planned for her brother, but nothing seemed to happen. Maybe a number of settings need to be changed, she reasoned.
Heck, shes played sims before, she knows how to make a character! She was unsure what character to make, but with a chuckle she let her imagination go wild and before she realized it. she replaced her brother's original stats with that of... and clicked save.
(in reading the options below, bear in mind, she thinks this is a mean joke to hurt her brother, so she may put crazy things in to get the program to reveal its cruel intent.)
