Don’t put the cart before the horse

Don’t run away with the idea!

Don’t put your head in the lion’s mouth!

I don't know what to say.

Don’t let it get you down

Don’t always take everything personally!

Don’t get impatient!

Don’t spare the horses!

Don’t fuss so!

Don’t let yourself be fooled!

Don’t strain yourself!

Don’t beat about the bush. Tell me plainly what you mean

I don’t expect her to.

I don't think it will last long.

Don’t get arsey [with me]!

Don’t sweat it!

Don’t halloo till you’re out of the wood!

I don't understand.

I don't want to say anything.

Don’t get it twisted!

Don’t touch!

I don’t suppose you know that?

Don’t get upset

Don’t get yourself in a tizzy

I don't want to complain.
