Oh dear, I've made the unforgivable internet mistake of imagining that the lighthearted tone of my first post would carry into my second one, without needing to be re-stated. Bad, bad me.
No, I expect nothing of other adults. Internally though, there is a small voice that beseeches them, 'please notice there's a 2 to 3 yo approaching right behind you and don't press...' Never works, no.
Any fule knowe that, once the 'wait' light is activated, there is no satisfaction to be gained by pressing the button. Be that at a crossing, for a lift, or pressing the bell on a bus.
Any 2-3yo knows that it is just too disappointing if an adult, just ahead of you, has pushed the button. Whereas, if other children there at the same time, a discussion about nice sharing is justified.
Would I miss a stop on the bus because we didn't press first? No. But have a I waited out a cycle of lights, so dd, when aged 2-3, could press and gain the satisfaction of stopping the traffic (at the kind of stop where the lights only change if a pedestrian presses)? Hell yes.
There are moments for discussions about sharing, needing to be somewhere on time and life just not being fair. There are also moments when indulging something fun, or because the upset isn't worth it, is totally fine IMO.
I'm glad FloydOnThePull gets it!
