Hi Roman
In CT we don’t use many non standard (Eng/French) expressions.
Some of the ones that we use in Portuguese are:
BD - Bom dia = Good morning
BT - Boa Tarde = Good afternoon
BN - Good evening = Good night (From sunset to dawn)
AB - Abraço - Hug
Obrigado - OBG = Thank you
Most of the time we use plain Portuguese.
