Just thinking

Christmas is a cool time. Both the literal meaning and the cool meaning as in class. It's a time for happiness and sadness, and an evaluation of life and a looking forward to great shopping deals. It also happens every winter. Winter is good because you tend to get snow when it's very cold. Snow is made up of tiny crystal flakes with beautiful patterns. You can also get crystal glass. Glass is fantastic. Windows are made out of glass, they provide a barrier to the elements but while also letting light through. Light travels very fast indeed, the light you see from stars can sometimes be millions of years old. There is a constant time throughout the entire universe, but if you focus on light from old stars you can get confused. Time also has a start and end, just like this blog.
