How did we ever function pre-"mobile phone era"? I know how we functioned pre-internet.. slowly! Mail used to take 2-4 weeks to get half way across the world and we had to go to the library to research information. Encyclopedia's played a big part of our life and we weren't as knowledgeable about the rest of the world and its events.
But without mobile phones, how did we ever manage to meet up somewhere? Now-a-days, we constantly use our mobile to figure out where the other person is, when they're arriving, and where we're meeting up. "Wainkom?" "3ind el food court.. yala ta3alay!"
Imagine your mobile taken away from you for a few days. Will you be able to function?
