What is the neutral way of telling someone to "do whatever you want"?
Do whatever you want
This sentence can carry a negative tone (highly probable). Making it sound that someone is fed-up and/or simply doesn't care. Especially after one has had a heated discussion/argument.
How can I tell that in a manner that it carries a neutral and preferable a positive tone?
Solution 1:
Plenty of options for this one. All of the following can be made to sound snarky if said with a sarcastic tone, but none of them carry an inherent negative connotation.
It's up to you. OR I'll leave it up to you.
It's your call.
I'll let you decide.
Let me know what you prefer.
It's up to your discretion.
You're free to choose.
...and more.
The choice between these depends a little bit on context. If you're trying to convey that you want them to choose, but that you don't need a say in the choice, I'd personally choose "Let me know what you prefer," because I want to stay in the loop.
If, on the other hand, I'm trying to say "I don't care what you do" in a polite way (simply saying that I'm not affected by the choice), I'd lean toward "It's up to you."
Again, it depends on the situation, so when deciding which to use, it's up to you. ;)
Solution 2:
A neutral version would be, "As you wish." A more positive spin on it would be something along the lines of "I'm sure you will make the right decision" or "No matter what you decide, I will back you up."
Solution 3:
The phrase feel free has a fairly neutral to positive tone, as in
Feel free to do whatever you would like.
But do bear in mind that almost any phrase can be negative when delivered with a good dose of sarcastic tone.
Solution 4:
In legal documents you might see
"Please govern yourself accordingly."
Colloquially, you might write
"Please act accordingly", or just "Act accordingly."
I think these are quite neutral but much more formal.
