This couple both saw me at the same time (my technique needs work here). But they are in stride together, they incline their toward me together, their expressions are not a million miles apart from each other. The two guitarists eyeing the cyclist have only their guitars out of sync' with each other and the mother and daughter (my supposition) walking out of frame are clearly quite close.
The group here are "on a mission" striding along and not noticing me; by this time I had taken one shot and then decided to squat down and take a picture at "their" level. It might have worked better if the lead female (not sure whether she was a young mother, elder sister or carer) was looking at me or straight ahead.
