Clearly, the ability to be outside in appropriate clothing for activities isn’t being mandated. This is where a temperate climate enables ridiculous practices to persist.
All I can think about when I see this image is how in Ontario, the responsible provincial ministry requires all schools and ‘day nurseries’ (read day and after school care) to put the kids out in the yards twice a day unless the weather conditions are severe (Less than -20 or more than +30 Celsius.).
Parents are responsible to send their kids with suitable clothing for the cold. One rarely sees little girls in skirts in schools unless they are wearing tunic dresses over leggings.
In an earlier era, pre 1970s, when skirts were mandatory for girls, that meant switching to pants or snow pants from the skirts 3 times a day to go outside in winter (two breaks and leaving end of day).
Or just tag one of the artists who posts on Mastodon. They’ll get the notification and can decide whether they want to respond here or not.
Vfx head Brian Tatosky did that when I that on another post.
Unfortunately, I can’t recall which of the animators have seen posting on Mastodon.
