Or… turn yourself into a field mouse and then build the snowman…
Having just explained one thing (that it is easier to write about something you have experienced than it is to write about something you have not) I would like to say the opposite!
For certain folk, imagining is easier than recalling. This is mysterious, I grant you, but true.
It is good to get to know yourself as a writer. If you suspect you are one of the Tribe of Very Imaginative Types, and you are given the writing prompt:
Describe how to build a snowman
consider all of the options available to you.
• You are not a human, but a field mouse coming out of a den during winter. You are building a field-mouse-sized snowman and even one wet, spring snowflake feels heavy and difficult to carry to this tiny, whiskered architect.
• You are building a snowman in summer, and you have to do it from the shavings of ice cubes from your icebox. You quickly transport the shavings out to the shade of your garage, the coolest place you can find, but they are melting, and you’ve only got minutes before they become a grease-stained puddle. You see, you need to build this snowman, because he knows the answer to an important question.
• The snowman is slowly coming alive as you build it, and then reaching for things and helping you with his spindly twig arms.
The possibilities are too many to list!
You still have to come up with a snowman. But if familiar circumstances make you feel stuck and invented circumstances make you feel free, ask your teacher if you can work with a writing prompt in this way.
