Yes, I know the expression 'to kick the bucket', I meant I never saw the expression 'to turn the corner' for recovering after illness.Not sure where you saw the expression "kick the bucket" but it is a common term in English. It has been around since the 1700's apparently and may come from the idea that a person wanting to end their own life would stand on a bucket, place a noose around their neck and kick the bucket away. There are other explanations, but I don't know them. Certainly it has been in use for about 250 or 300 years.
The giggle was because the translation means kicking the bucket in Dutch (so that's how I read it for a second before making sense of the post), not something you usually say to people who are feeling unwell!
