Dd (just gone 6 months) in the sling on my hip, with her head tilted back looking at the sky. In no danger whatsoever, perfectly secure. Middle-aged woman comes rushing up, pushes dd's head up, whose head snaps up alarmingly and shrieks, "She's not safe in there!"
I was very close to smacking her one, but was more concerned for dd, just turned my back on the woman so dd was safe and walked into the nearest shop - which, luckily, was the comic shop where I know the owner very well.
