...as in "not too big".

Mrs S pushed her fingers and thumbs together to indicate the size of the Bramley cooking apple she wanted me to buy this morning from across the kitchen table...I wasn't quite sure how to process that particular piece of information. The challenge was then extended to "2 sweet potatoes - again not too big" and "tub of greek yoghurt, not too small"...hopefully I met her expectations on all the items...
