And no smart arse ones like "We are moving to Staffs."
It's one of ds1's spellings - they are all singular and plural words, some regular, some irregular - he has staff and staffs. I just had a bizarre phone conversation with Troutpout (her ds is in the same year) with all our kids yelling in the background so we couldn't hear each other and her going "so is it staarf and staarfs?" and me going "yeah, staff and staffs" (bl@@dy Southerners). We couldn't come up with a good use for the words staffs - apart from my rather pathetic "The assorted Biblical folk gathered their staffs and set off across the desert."
So staffs...
This isn't part of the homework, btw - we're just puzzled!
