With 3 out of my 4 dcs today in a busy Carluccio's cafe near home. Wave hello to school acquaintance and her dd across the room. Later take ds3 (3.7) to the loo, just as acquaintance enters next cubicle with her little one.
Ds does his wee. My turn next. Cue in his foghorn voice "Why is there a little rope hanging out of your bottom mummy ?"
