"Learning to deal with people looking at their cell phones during conversation"
I immediately stop talking and if the person notices, they will usually apologize. If they don't notice after a few seconds then i turn and walk away.
Call me crazy but I don't have a cel phone. At home I have a computer and and work I have a computer so I don't really need one in between, or when I am out and about enjoying myself. I guess I am an extreme minority now, but I will never be one of these zombies you see everywhere. I like to be aware of what is going on around me. I believe that not connected time, simply staring at the scenery on the train for instance, helps one to think and process things. No one thinks anymore, they just look down at their phones and distract themselves.
I can appreciate that cel phones are a useful tool, but the way people treat them is so bad I can't stomach the thought of owning one.
Not to mention all the persistent tracking and other horrible privacy concerns. Not to mention the upfront multi hundred dollar cost and the $50+ monthly cost... I guarantee that the only phones I ever own and use will be feature phones that make and receive calls only. I don't need a little TV turning my mind to mush and tracking me all the while.
