Fairly distinctive pair
I almost put a young boy in the canal once. His mistake. Rather, his mum's mistake. Combination of trying to look behind at Mummy going "Look out for the man on the bike", brake and steer all at once. I slowed and pulled in to the left to let him pass on the safe (non-canal) side but he tried to take avoiding action by going the "wrong way" around me (i.e. through the weeds and not along the towpath I had left for him). He somehow bounced and rattled past without ending up in the drink.
Both myself and mummy had a heart in mouth moment. My friend - a few metres behind me - found it rather hilarious.
I've found parents and dog owners who call their charges roaming ahead of them to heel cause more problems than they intend, as first reaction of child / dog is to try look behind them. The children generally do that thing that youngsters on bikes do which is swerve to one side as the little arms follow the neck around, taking the handlebars with them. Dogs generally stop dead, turn broadside across your path and then completely ignore you as they focus on the owner.
It's simplest just to slow and pass like ships in the night.
