Tough it like a viking.
Pigerne kan begynde at svomme i december i Australia.
In an indoors pool...
Sounds like it's Australia :D
That doesn't sound pleasant! They could get hypothermia!
If there is not a modal, we would have to write :
"Pigerne plejer AT begynde at svomme i december"
Am I right or definitively not? ^^
I would say it's without "at" but I'm also just a learner so idk
