comment The logic behind “better safe than sorry”
It is not clear that being safe is better, since to be safe one has to forgo dangerous things and those things often have benefits and advantages. Those may or may not outweigh the safety benefit.

comment saying “hello” when somebody asks something obvious
"Back to the Future" probably increased the usage. "Hello? Hello? Anybody home? Huh? Think, McFly. Think!"

comment Is 'my wife and I' correct English?
It depends on context. What is proper in an informal context is not always proper in a formal context. However, "I and my wife" is basically never used.

comment Is this sentence a run on? How to properly use 'such as' for this example?
Removing the comma after "unveiled" is sufficient to make it grammatical.

comment What does “tit-for-tat” mean?
What is "tat" anyway? And how can I get some? And then how do I trade it?

comment Difference between “submittal by” and “submitted by”
One tells us who wrote it, the other tells us who submitted it. Since those would usually be the same person, it typically makes no difference.

comment Difference between legacy and traditional?
@Joe.wang Traditional doesn't necessarily have any negative connotations at all. Legacy suggests that there's something newer and better and that it should/will be replaced.

comment Why do we use the word “oops”, if something goes wrong?
Do mean why specifically do English speakers use the word "oops"? Or are you asking why humans display the characteristic of speaking some word when they make or experience some kind of mistake or problem?

comment “With the purpose of” vs. “With the intention of”
"I've borrowed some Spanish DVDs from the library for the purpose of listening to native speakers trying to copy them." This sounds like you're going to get native speakers to try to copy the DVDs for your listening pleasure.

comment Meaning of “let bygones be bygones”
To let a bygone be a bygone is to make that which is in past stay in the past and thus not affect the future.

comment In my example, do I need a comma before which?
It depends what you mean. What implies a large bias? The changes in the arrests rate? Or that the linear fit fails to fit the age profile?

comment Differences in uses of efficient and effective
@user1515834 You can execute a task efficiently but not effectively if you execute the task using few resources but in a way that doesn't give the desired results for reasons outside the scope of the task itself.

comment Between you and (“me” or “I”)?
@Henry Except "between you and I" has been consistently used since the mid 1700's -- that's way too far back to be hyper-correction.

comment Between you and (“me” or “I”)?
Your argument is circular. It does show that "between we" is wrong and "between us" is correct. But it doesn't help with "between you and me", because we don't know that "you and me" is a subject. If "you and me" is an object, then "between you and me" is fine, just as "between us" is fine. If you're saying "between [x] and [y]" must behave like "between [x] and between [y]", I'd argue there is no such rule. Were there such a rule, "The dog and cat is missing" would be correct.
