chktexparentheses
While running chktex, I get this error
Warning 36 in file.tex line 2062: You should put a space after parenthesis.
pen(s)
I am writing the word pen but I am adding an s in parentheses as an option for a plural form (pens). The final result I want is pen(s).
I just want to make sure there is nothing to worry about in the final build. Or, if there is something to worry about, how do I fix it? I am also NOT in math mode.
The chktex manual says this:

When you change the order of the packages lmodern and MnSymbol to
\usepackage{lmodern}
\usepackage{MnSymbol}
than you get the parentheses again.
When reading the code, TeX gobbles spaces directly following a control word.
Compare
\LaTeX is great.
vs
\LaTeX{} is great.
In this case a warning makes sense.
I am assuming TeX was designed this way because in TeX programming it improves readability if you are able to insert spaces.
Please note that spaces are ignored after control words only, not after control characters or active characters. Consequently ~␣ would insert two spaces and should therefore be avoided.
A control word starts with exactly one character of catcode 0 (usually \) and is followed by an arbitrary number (greater than 0) of characters of catcode 11 (letter).
Example: \LaTeX
A control character starts with exactly one character of catcode 0 (usually \) and is followed by exactly one characters which has not catcode 11 (letter).
Examples: \␣, \&
An active character is exactly one character of catcode 13.
Example: ~
For characters with math code active (for example ') this is irrelevant because spaces are always ignored in math mode, anyway.

As the maintainer of ChkTeX I give you permission to ignore this warning. :-) Most things in ChkTeX are just that warnings. They aren't errors. It's meant to warn you of things like "I went to the store(the small one on the corner)" where you forgot to put a space before the parenthesis.
If you find this is never a useful warning for you, then simply turn it off in your
chktexrcfile, or you can turn it off on that single line by adding a comment like
