There is truly nothing more that grinds my gears than when somebody is texting me and facebook chatting me at the same time..Why can't a person just pick one?? Someone will send me a text and then ill just respond to that person on chat adn then they won't respond on chat and will send me a text answering the question I posted on chat! That drives me nuts! Perhaps some people do it on purpose just to be irritating.. Or maybe they dont even realize they are doing it! I am not sure.. But that is definitely something that grinds my gears! Technology is great but too much of it can become very overwhelming!
