Why it feels like the right thing to say

You mean it kindly. You’re saying your time matters more than mine, you choose. It feels flexible and low-maintenance and unfussy.

And then nothing gets planned, repeatedly, and neither of you understands why.

What it actually does

“Whenever” is not information. It’s an empty set wearing a friendly face, and it hands the other person three jobs at once:

Work out their own availability
Guess at yours, because “whenever” is obviously not literally true
Propose something, and carry the risk of it being wrong

That third one is the expensive part. If they propose Thursday and you say “ah, not Thursday actually” — which will happen, because “whenever” was never true — they have now been refused for doing the work you declined to do. Twice of that and they stop proposing.

The generous-sounding answer moves all of the effort and all of the exposure onto the other person. It’s the opposite of what it feels like.

The other thing it does

It also hides what you want. “Whenever” from someone who’d love Friday and would tolerate Monday reads identically to “whenever” from someone with no preference.

So plans get made on the wrong days, enthusiasm quietly drops, and nobody can point at why. The information that would have fixed it was available and got suppressed for politeness.

What to say instead

Name two or three real windows. “Thursday after 19:00, Saturday afternoon, or Sunday morning.” That’s an answer. It can be worked with, and it can be refused without anyone feeling rejected — a window isn’t a proposal.

Say which you’d prefer, if you have one. “Saturday’s best.” One clause, and it saves a whole exchange.

If you genuinely have nothing, say that. “This week is bad, next week is open.” Also an answer, and far better than “whenever” followed by three declines.

The version that scales

Doing this out loud every week is tiring, which is why it lapses.

The alternative is to state your availability once, somewhere you can both see it, and let proposals happen inside it. That’s what painting your week is: not a promise, just “these are the hours I could give”. Your partner proposes into a window that’s already real, you’re not guessing at each other, and a decline is about the plan rather than the timing.

Hours for Two exists for this specific exchange. Where your hours and theirs overlap, there’s something to propose; outside it there’s nothing to ask about. “Whenever” stops being sayable, which turns out to be the point.

A note for the person who always asks

If you’re the one always proposing and always hearing “whenever”, you are probably tired, and you may have started reading it as indifference.

It’s usually not. It’s usually someone who thinks they’re being easy to be around. Worth saying out loud once, plainly: “whenever” doesn’t help me — give me two days and I’ll pick one. Most people have simply never been told, and they change it immediately.

TL;DR

“Whenever” is not information; it hands three jobs and all the risk to the other person
It hides your preference, so plans land on the wrong days for no visible reason
Name two or three real windows, and say which you’d prefer
Stating availability once, visibly, beats renegotiating it every week
If you’re on the receiving end: say so plainly, it’s rarely indifference
