In the realms of numbers, a lone digit attracts hoards of notice from writers. Proof of that are “The Three Muskeeters,” “Three Blind Mice” , etc.
Another confirmation of the fact is in novels. The protagonist generally teams up with duos therefore summing up into trios. A book of that example is Harry Potter Series. (Wingardium Leviosa)
So, writers, what is in three? Answer me! Google does not show anything ( or maybe I just don’t know what to search.)
