Sometimes it’s good to care. If someone is saying you’re acts are immoral irresponsible or genuinely with your interests in mind you should listen and make a decision. If its someone saying you’re being odd or being weird they’re projecting their own self consciousness to stand out from the crowd.
My gf got an iPhone last year to try and experience it. I’ve thing she uses her phone a lot fit is movie consumption. Iphone doesn’t let you transfer files from a pc to it by just plugging in the USB and using the file manager let me tell you. She is pissed.
