Logic behind 'Myna - one for sorrow, two for joy' superstition

|THE DEN|

Myna - one for sorrow, two for joy

Belief - One for sorrow, two for joy, three for a girl, four for a boy, five for silver, six for gold, seven for a secret never to be told, i.e, if you see one myna you will be surrounded with sorrow while seeing two mynahs will bring joy and so on.

Logic - It’s just a fun rhyme and nothing more than this.
