## Common Mistakes to Avoid
### **Mistake 1: Using Slang in Formal Settings**
– Job interview: “대박!” ❌
– CEO meeting: “완전!” ❌
– Formal settings: Use 대단합니다, 정말요? ✅
### **Mistake 2: 거짓말 Timing**
Used at wrong moment sounds accusatory!
– With strangers: Be careful ⚠️
– With close friends: Use freely ✅
### **Mistake 3: Forgetting ~요**
Casual speech to strangers/elders = rude!
When unsure, ALWAYS add ~요!
### **Mistake 4: Overusing 완전**
완전 is youth slang – sounds odd from older speakers!
Age-appropriate alternatives:
– 정말 (really – all ages)
– 너무 (so – all ages)
– 완전 (totally – youth/casual)
### **Mistake 5: Wrong Reaction for Situation**
– Good news → 대박, 축하해 ✅
– Shocking bad news → 헐, 어떡해 ✅
– Disbelief → 거짓말, 진심? ✅
Don’t use 대박! for bad news!
