I've walked out of class in the middle of a lecture to take a phone call before and when I walk back in I just tell the teacher I was trying to be courteous, lol. Aside from that, more than 50% of any given class I have my cellphone in my hand texting someone. Hell, even during finals I'm texting people and teachers never notice. Only once did I ever get my phone taken away and I made such a big deal about it the principal just gave me back my phone. Aside from that, hell yeah gaming all day long.
