- Stop talking on your cell phone when you drive.
- Stop talking on your cell phone when you use a public restroom.
- Stop talking on your fucking cell phone at the movies.
- And for the love of Christ, stop talking on your cell phone while you rape.
I don't give a fuck if you think it "isn't an issue" in how you go about your daily life: you're wrong. You drive stupidly, you sound like a dickhead in the toilet, you're ruining the movie and you're even raping poorly. Cut it out.
Context always uses a cell phone when it's proper to do so.
