N3.5yo is now into the idea of opposites: short/tall, up/down, etc. So I asked for things he had not practiced. He thought about each for a few seconds.
The opposite of spoon? “Fork.”
Sick? “Ambulance”.
Kleenex? “Sneeze.”
Lego? “Taking away legos!”
Nice to see you here. Let me know if I can help you with orientation ... the dynamics on Mastodon in general, and Mathstodon in particular, are different from those on Twitter and Facebook, so I'm happy to help get you settled.
