My ds (9) writes stuff like the hippo analogy. Thank god he's not doing 11+
His teacher last year: "He has not got a single ounce of imagination. I've never seen such a boring story"
Me: "It's got a, um, dragon, knight and big battle in it. He had to imagine those"
Teacher: "But there is NO DESCRIPTION!!!"
Me: "But wouldn't it be rather 18+ blood and gore if he did?"
Teacher, unsmiling: "That is not the attitude"
Me to ds afterwards: just stick in those describing words syou say are boring and get in the way of the story to keep her quiet. No battles, mind.
Sort of worked for a bit.
