Could you have a three hour conversation with another person without checking your cell phone?

Yes.

Of course

Yepp. I make a point of it, actually. I've also asked my mom to put hers away on multiple occasions. Usually while eating out, before, during,nad after the meal.

Yes. I always put my mobile away when talking to someone, no matter how long it takes.

I definitely could, once. I probably could again.

I've never owned or used a cell phone - - and my land line phone doesn't work.

Probably if they were interesting. I can usually talk the hind leg off a donkey.

I can't see why not.

yes
