To me "Best Regards" always sounds like some has mashed together "Best Wishes" and "Kind Regards". Of those two "Best Wishes" can be used when you have a close relationship with the recipient and "Kind Regards" seems appropriate for someone you have met before but still have some level of formality to the relationship.
Hugs in Portuguese is ABRAÇOS.
the Portuguese for garbage is 'lixo'
The word for "twins" in portuguese is "gêmeas"
You say "feliz".
