My generation is probably your generation. Talk about arrogance--you should look at yourself.

So I assume you'd have no problem if your date pulled our his/her phone and completely ignored you? If your boss called you over and spent the next half hour on his phone, that shouldn't be a problem. If you ask a friend over to talk because you're hurting, and he ends up on his phone the whole time, that shouldn't be a problem either right? If you fly across the country to see someone, and they ignore you completely for two days while being buried in their phone, that's not a problem?

Is this a generational thing? No, you're just being a selfish asshole by talking on the phone when you should be giving others your attention. What arrogance indeed!
