Best practice
Use "so will I" to clearly and concisely express agreement with a preceding statement, ensuring the auxiliary verb matches the original statement's tense and form.
Common error
Avoid using the wrong auxiliary verb. Ensure the auxiliary verb ('will', 'do', 'have', etc.) matches the tense and form of the verb in the original statement you are agreeing with. For instance, if someone says "I have finished", you should respond "so have I", not "so will I".
