Sharon Standifird used to be upset when her son ignored her calls or texts. She has changed this with modern technology.
　　After a few months of design， she developed an app called “Ignore No More”. The app can control the phone of her son， Bradley， once it is installed onto the phone.
　　Bradley needs a password to unlock the phone， and only his mom knows the password. He can’t call or text anyone but his mom when the app is running. The phone will let him call 911， but won’t allow him to use the Internet or play games.
　　“Bradley needs to call me because I’m the person that has the password，” Standifird said. Her husband William is not surprised at the abilities of his wife， who served in the Gulf War. According to William， Standifird can do whatever she wants. “I just started researching how to develop an app，” said she.
　　Standifird said the app had changed her son. To make sure his phone is not turned off， Bradley has been texting back and answering her calls. “It was a good idea， but for other people， not me，” Bradley said.
　　What is Bradley’s attitude toward the app mentioned in the passage？
　　A. Welcoming. B. Indifferent. C. Unhappy. D. Angry.
