This is so not the moment.
Not the moment to tell a frazzled-looking mum that it must be fun to be home playing with the kids all day.

Yes, lockdown was and is hard on everybody. Behind the "introvert's dream" memes and online yoga classes there's a mental health epidemic unfurling. Isolation, anxiety, depression. Beyond Blue report that from April, calls to their reach-out services were up 66 per cent. That's a lot of people struggling to cope with the new reality that they may and will be cut off from the world at little notice. That their livelihoods can be snatched away. That jobs can dry up.

They're learning how to behave in a crisis.
