Part 6: Common Mistakes to Avoid

Over-Apologizing

In English-speaking cultures, excessive apologizing can seem insecure:

Too much: Sorry, sorry, I'm so sorry, I feel terrible, I can't believe I did that, please forgive me...

Just right: I'm really sorry about that. It won't happen again.

Matching Tone to Situation

• Serious mistake + casual apology = Seems insincere
• Minor slip-up + overly formal apology = Feels awkward

Tips for choosing the right apology:

1. Assess severity - Simple expressions for small mistakes, formal apologies for big ones
