Richter will have to continue helping her by pushing her a while longer, but eventually she will figure the right kind of movement out and swing higher and higher on her own, grinning widely.

Yes.

She finally figure it out.

Her elation stays for a while, and it takes a bit longer after for her to grow ...not bored, but not highly interested anymore, with the activity. Ten minutes, perhaps.

She could just stop swinging, but... she has seen people jump from swings, using the momentum for a nice high curve, and she definitely wants to try that. She has to get lower first because she will crash into one of the other metal constructions on the playground otherwise, but then she lets go as she's reached the highest forward point and flies, hitting the dark ground with the grace of someone with perfect balance and much practice in jumping down from higher up places.

She almost immediately bounces to her feet and swings around to walk back towards Richter, if he's still around.
