Why does it take the sun?

We have just gone onto daylight savings time here; though I often wonder why it is termed that as we are not really saving daylight, rather the intention is to use up far more of it.

While walking with another Mum last week, I became totally animated in conversation by the fact that once bub had go to bed for the evening I could now actually pop into the city and visit stores that were open late.  It was like I had found a key that opened a door into some magic world!  It then dawned on me that I could have gone to these shops the entire winter, as their hours do not alter.  But somehow it is only now with the light that makes it seem a real possibility.

Why does is take the sun?  Clearly I am part bear, and with the onset of spring I am emerging from hibernation!
