my phone

I was texting my friend last night during a movie and then i told him i had to go to bed. But then he called me. I told him to not call so late. He called and i hung up then i called him back to tell him to not call me but i accidentally put it on speakerphone and my dad of course heard it and took it away. So i think i now have decided to turn of my phone at night so nobody calls me or texts me late at night.
