Expert writing Tips

Best practice

Use "so do I" immediately after someone makes a statement about themselves to show agreement, creating a natural and responsive conversation flow. For example, "I love hiking. So do I."

Common error

Avoid using "so do I" when the initial statement uses a different auxiliary verb. For example, if someone says "I have been to Paris", the correct response is "so have I", not "so do I".
