I really hate talking on the phone, not only the cell phone. The useful information that is exchanged is really too little and too much time is lost. Of course I talk, when I want to hear someone's voice.

And I don't really like answering the phone, because it's nearly always on business and somebody wanting something from me.

That's not exactly inspiring ;-)

I also text before calling when it's maybe inappropriate to call. "Is it ok to call?" "Call me if you are awake" or simply "Awake?" or "I am available".

I check my voice mail only if it is from an unknown number. Otherwise I just call back.

You're quite right about the answering machines. They were in scarce use only for 5-6 years in the nineties and that wasn't enough to build a culture.

And last but not least, the first time Bulgarians really had a free access to the phone, it was the cell phone. The wired phone was a luxury for the whole 20-th century.
