Strange things us humans aren't we. At some point way back in the mists of time a very clever bloke thought it would be a good idea to start calling this time of year Winter. And, as if that wasn't clever enough, someone else invented the month of January (I think it was the other blokes brother but I can't actually prove that). Anyway: once the people in charge told the rest of us we had to start using seasons and months, everyone at the bottom of the ladder of importance; (that's mine and your ancestors), started to notice the day's getting longer towards the end of January. Yet, and here's the strange bit, despite this going on for hundreds and hundreds of years we always seem surprised because it's still daylight at teatime.
So, to cut a very long history lesson short, that's why I'm here today, because that little bit of extra daylight has allowed me to get out for a short walk after work. Plus the fact that the sun is shining, but that's a completely different thing which I don't really have time to explain.
