با تشکر از جواب شما 1+ ولی فکر می کنم این معنی دست به دست هم دادن میشه
 

Answer 2

To eat from the same (a joint) dish هم کاسه شدن

To share source(s) هم کاسه شدن

To become confocal / concurrent / coincident

Autumn and Winter shared source(s) resulting in snowing & raining together. 

Autumn & winter source sharing ended up in snowing together with raining.

Autumn & Winter mixed up and thus it both rained and snowed together.
