My biggest pet peeve would be when people text. I cannot stand texting, I believe that if you can't call the person to talk to them, then you shouldn't be texting. When you are trying to have a discussion with someone or trying to hang out and they cut you of for a text really bugs me. I get mad when they can't go 30 seconds without a text. I much rather talk in person and if I can't then I'd rather give the person a call. I do whatever I can to stop the texts without making the person mad. When they are around me or if we are doing something I ask them to not text or keep it to a minimum because it really bugs me. For the most part people listen. My girlfriend is the only one who argues that it's not that annoying and that she needs her phone but in the end I'll just take it for the time that I'm there.
