Is it just me...?

Over the last few days, I've actually made a few trips to shops to buy Christmas presents, and I've notice that an increasing number of the great British public wander about without paying any attention to where they are or what anyone around them might be doing. If they drove cars like they walk, there would be total carnage. Why can't people look what they're doing and what those around them are doing? People block access ways with shopping trolleys, walk with a phone to their ear and simply stop for no reason and are then surprised when someone bumps into them. Wake up you dozy sods, there are other people on the planet besides you.
