Expert writing Tips

Best practice

Use "I'm supposed to" when indicating a general expectation or agreement, rather than a strict command. This softens the tone and implies a shared understanding or plan. For instance, "I'm supposed to bring the dessert" is more collaborative than "I have to bring the dessert."

Common error

Avoid using "I'm supposed to" when you mean something you did regularly in the past. "I'm supposed to" indicates a current obligation or expectation. For past habits, use "I used to". For example, say "I used to play the piano" instead of "I'm supposed to play the piano" if you no longer do so.
