Why is “things do occur” correct but “things often go wrong” is wrong. Is it because of the presence of “often” ?

[color=blue]You have to be a pessimist to say that things often go wrong…???

Accidents will happen and things do occur both are idiomatic phrases which basically mean that sometimes things go wrong.[YSaerTTEW443543]

Ok, thank you. so I basically need to remember that they mean the same.

As an aside, what is the difference between “happen” and “occur”. Do we use “happen” when things happen unexpectedly and “occur” when an event occurs as expected?

Also in general what is the rule/accepted custom to post these lead-off questions which don’t really have a connection to the original post?

Thanks again
