Yeah. But for some reason more people prefer having dinner at day time and getting up to work in the freezing night time.

My parents simply disregarded daylight savings. Our routines always have and always will be more in line with the sun. A clock is just there to confirm the sun’s around where it should be.

Your daughter’s not going to want to do the thing in the routine because you’re expecting her to do them at a time of day that isn’t the right time of day to do them yet. Her circadian rhythm and perception of the day gives zero fucks about the concept of DST so just remove it from her.

I sympathise that they are currently in a period in their life where they are doing door-to-door sales for a wage.

It’s easy.

1. Deny
2. Take control
3. Show empathy
4. Start their departure.
5. Make them glad they’re leaving

Cut them off, “Oh, sorry. I’m not interested in that. I need to quickly get back to what I was doing. But you have a good day and try stay cool/warm/dry/etc. out there.” Start stepping back, “And be careful of the dog four doors down, it’s a fucking cunt.”

As you close the door, say “You too, bud.” regardless of what they say, even if they say nothing.

They will never return or pursue, and you won’t feel rude.
