Question: I am wondering if anyone might have a suggestion about how to request to be addressed by a personal title and one's surname. For example, I prefer to be addressed as, "Mr. Redgate," but I do not wish to come across as rude. I was taught that it was rude to address someone by their Christian name unless that person has given you permission to address them as such; we were admonished for being too familiar.

I am not fond of most people calling me by my Christian name and especially the abbreviated, "Joe," "Jo Jo" or "Joey." Such familiarity, especially by people with whom I am unfamiliar, is quite offensive to me. What is frustrating is that I know that if I politely request that they refrain from such addresses, I am the one who is thought to be rude.

Does anyone have any suggestions?

Answer: 
No, the word *both* can't be used in this way. *Both* only ever refers to two things, never three. You don't need to use anything before the list. the fact that you list all three things and follow it with the third-person plural conjugation of the verb *utilize* indicates that all three items listed constitute the subject. However, if for whatever reason you want to use something like *both* that you could use for three things, then write it as follows:

> 
> All three, method A, method B and proposed method C, utilize ID
>  information, which makes these methods depend on number size.
> 
> 
> 

-or-

> 
> Method A, method B and proposed method C utilize ID information, which
>  makes all three methods depend on number size.
> 
> 
> 

-or-

> 
> Method A, method B and proposed method C all utilize ID information,
>  which makes them depend on number size.
> 
> 
> 

Be sure to note the correction to the conjugation of *depends* to *depend*.
Three things happened at once; a, b and c

Three different things happened; a, b, then c

Three conflicting things happened, a, b but not c
