Solo is a four letter word.
People often ask me if four letter words are supposed to be curse words. No... the truth is far more complex. A good four letter word is both a blessing and a curse. It is both good and evil. It shares the ying and yang.
Such is so very much the case with "solo".
On the dark side, it represents solitude... loneliness... instead of a partnership, one must go it alone.
And yet... one can be alone without being lonely. One can accomplish achievements by oneself.
