Isn’t it funny that “candid” can have two such different meanings? One can take candid photos, in which the subject is unaware of any such thing, and one can be candid (open, transparent, honest) about some matter.
So, I guess if one’s name isn’t Frank, one could say, “Let me be candid about that.”
However, it’s best to not let me be candid about anything, except perhaps my belief in God in the now and in the hereafter. Indeed, if only my name were Frank, I could speak freely about it all; however, I will say that, un-pc opinionated as I am, I may be thought to resemble on my inside what I’ve begun to refer to as my troublesome, traitorous little gall bladder (and the current WH occupants, as it happens) — “a pinch-faced pain the as(p).”
I rather hope the the WH occupants go away even sooner than the nasty gall bladder.
