In what situation can we use ""Bạn sắp sai."? Maybe your friends says "this year the lunar (Tet) new year is on a Tuesday". You say "no!, it's on Wednesday". You friend searches the Internet on his mobile phone and say's "Bạn sắp sai. ".
Is it okay to use it in this situation?
In English, I've mostly heard 'You are about to be proven wrong'.
