concern vs bother

[mrwroc]

I found the following sentences:

bother verb (WORRY)

https://dictionary.cambridge.org/dictionary/english/bother
1. I don't care if he doesn't come - it doesn't bother me.

concern verb (WORRY)

https://dictionary.cambridge.org/dictionary/english/concern
2. Does it concern you that your children are out after dark?


My first question:
I'm not sure if the dictionary definiction of 'bother' = 'worry' is correct.
If it is correct, I can change the first sentence ("I don't care if he doesn't come - it doesn't bother me.") to the following:

I don't care if he doesn't come - it doesn't concern / worry me.​

But, in my opinion the sentence above doesn't have sense, am I right?

My second question:
The second sentence ("Does it concern you that your children are out after dark?") means somebody worries about something. But, if I use 'bother', it means I don't care about something. Am I right?

Does it bother you that your children are out after dark?​

They're not the same. If I play my radio too loudly, it might bother you, but it won't worry you. I might turn down the volume because I'm worried that you're going to throw it out the window. But I'm not bothered.

If it is correct, I can change the first sentence ("I don't care if he doesn't come - it doesn't bother me.") to the following:

I don't care if he doesn't come - it doesn't concern / worry me.​

You can. The meaning will be slightly different.

But[STRIKE],[/STRIKE] in my opinion the sentences above don't make sense. Am I right?

They make sense.

My second question:

The second sentence ("Does it concern you that your children are out after dark?") means somebody is worried about something.

Yes.

But, if I use 'bother', it means I don't care about something. Am I right?

No. If it bothers you, you care.

Does it bother you that your children are out after dark?​

There are not many words that always mean exactly the same thing as another word. Some words mean the same thing sometimes. Worry, bother, and concern are good examples.

The dictionary is not actually saying that 'bother' = 'worry'. It's just saying that there is some sense relation between those two words. That doesn't mean that they can be used interchangeably.

If it is correct, I can change the first sentence ("I don't care if he doesn't come - it doesn't bother me.") to the following:I don't care if he doesn't come - it doesn't concern / worry me.
But, in my opinion the sentence above doesn't have sense, am I right?

Yes, you're right. You need bother in that sentence. The dictionary example is meant to the show the use of (not) bother to mean that you don't really care either way. That is to say that you don't have a preference as to whether he comes or not. A common variation (in British English, at least) of (not) bother appears with bother in an adjective -ed form. I'm not bothered = I don't care either way.

My second question:
The second sentence ("Does it concern you that your children are out after dark?") means somebody worries about something. But, if I use 'bother', it means I don't care about something. Am I right?

Does it bother you that your children are out after dark?​

Don't use bother in this sentence. You can use either concern or worry, with the same meaning.

I'd generally use "bother" to mean something like "make annoyed" in these kinds of contexts. (There is another way to use it.)

Does it bother you when he whistles while you're trying to write a report?
Stop bothering me!
If you bother my son again, I'll make sure you're separated in class.

And you have hot and bothered for when someone is agitated.
