Almost 1 in 5 NZ Delta cases are children

  I don't think that's altogether a fair comment; there was no indication of a 'cavalier disregard for the safety of children' - just a different way of seeing this.
If it was up to me, parenting classes would be compulsory in high schools, using the lifelike dolls & including basic budgeting, cooking, gardening as soon as it could be set up, & parenting classes for all new parents likewise, with classes (free) to all existing parents who want a bit of help. And for those who exhibit really dire parenting skills as well - help & support to become better parents.

Going into mask mandated areas where there are others, including children, may be in close proximity is to show a cavalier disregard for the health of those vulnerable kids. this is why we fucking well mandated it. to keep people safe. 
to consider yourself ok to go unmasked for your own selfish reasons (its hot, its hard to breath. bullshit.) is both arrogant and flippant.

not on my watch.

There are not 'mask mandated areas'...  people are required to wear masks in specific situations, and some like myself have a mandated exemption from doing so.   

You might as well add to your list of 'selfish' reasons 'will end up in hospital by the end of the day' - that is my life at the moment if i wear masks for extended periods... selfish, not from my perspective? how does that make sense for anyone?

and where the heck you get this 'cavalier disregard for the safety of children' I have no idea, I suspect your just making shit up now... Grow up...
