ice

Ice is beautiful, isn't it? Just look at that picture or imagine crystals, snow... It's marvellous to look at structures that often seem so artfully crafted and who come into existance when plain water freezes.
Ice is also fun. Who hasn't ever enjoyed ice-skating, snowboarding or skiing?
Ice is delicious. Most of you will agree that there is nothing better than icecream, slush or drinks with icecubes on a hot summer's day.
So why do so many people hate winter and especially frost? Because it's cold, is a quick answer.
'As cold as ice' is more than a metaphor. We don't want to be cold. Nobody likes shivering, goosepimpels, a red nose, hurting fingers and toes.
Emotional ice climate is equally unpleasant. Someone who is criticizing you with a sharp, icy voice. A cold personality. A frozen relationship. None of these things is something you'd like, because they're like ice:
Ice is cold, motionless and hard. They ought to be smooth and fluent like water. The characteristics of ice, not only the stiffness, also the fact that it extends in the process of freezing, cause many problems in winter: Ice has the strength to break tubes and stones, harbours and rivers cannot be shipped anymore, mechanical devices are no longer movable... and people wish it would just melt because
Ice is destructive. Ask any installer, or anyone who knows about the fate of the Titanic. Or any gardener. Plants do only survive a limited amount of frost. All living things die when they freeze to hard, animals and humans too (we can just protect ourselves better). When the water in our cells freezes and becomes ice, it's  too late. They burst and get destroyed. Freezing is dying and ice isn't agreeable with living.
Ice is dead/th. Ironically it's always said that water is living - and both are just different forms of the same substance H2O, shaped by it's conditions. And still they're so different that the fluent water is basis for all life while ice has the ability to destroy it. Life and death are so close sometimes...
It isn't without a reason that most metaphors, connotations and literal images about ice are negative.
Ice's beauty can be as misleading as the fun a frozen lake promises
before one finds out that one has been walking on too thin ice and breaks in.
It's hard, destructive and can be very dangerous.
A very good illustration would be the Snowqueen in the fairytale and the White Witch in Narnia. She is beautiful but insidious and dangerous, holding the whole country in an eternal winter's grip and having the power to freeze everyone rock-hard. Both are the evil characters of the stories, living in fierce castles made of
Ice.

P.s. Something to add: There's always something stronger than ice - the sun wins the tug-of-war ever again (as in the stories where the evil Ice-queens always finally have to give in to the good ones who bring the summer)
