I'll start -
Child 1 - pleasure to teach, follows the rules, caring, sensible (well behaved super compliant little darling)
And ahem child 2 - real curiosity, naturally inquisitive, not afraid to take risks, easily distracted but can maintain high levels of concentration during child initiated activities (Only stays on track with tasks he chose, asks questions all the time and rather tricky all round
)
Just what I expected, but still made me grin.
