Daylight saving

I'm afraid I can't quite get my head around daylight saving. Seems to me having more hours in the day just means you run around more, doing more, then have dinner at some odd (late) hour, then you sit around for a bit longer as your brain is telling you it is just too weird to go to bed when it is still daylight. Then at the other end of the day it is still confusing as I am waking up with the light to find I have "slept in!"
