What is it with people and mobile phones?

One of my pet hates is the almost constant use of mobile phones by people while driving, shopping, dining, in line at the bank, etc.

Does no one know how to say, 'I'll call you back later?'

Well, it has gone beyond that now with phones being used in supposedly relaxing getaway places such as the beach.

For me this is just beyond inconsiderate.

While on the beach last weekend, I had to sit there and listen to this woman chatter on for at least half an hour as she pranced back and forth in front of me.

I couldn't concentrate on my book.
