Translation required

[aromulus]

Can anyone help with this translation?
Tanga ka kasi lagi kang walang alam! Manhid!
Deck

You don't always know - careless! Numb (no feelings)!

other version:

you dont always know coz ur dumb! insensitive!

This could easily have arisen due to a plain and simple misunderstanding between the people concerned.

I hope you are good at guessing what might be the bone of contention.....

Hope you make up soon.....
