Hi Amy, There must be subject-verb agreement in an English sentence. In this case, your noun (husband) is singular and should be matched to a singular verb (has). "My husband has drifted off to sleep." is the correct way to write. Hope this helps. Cheers, Lance

In a polyandric scenario, you might hear "my husbands have drifted off to sleep." Note how the word "husbands" is plural, and it agrees with "have". "They have" "it, or he, has". If it was "husbands" then it sounds like she's finally going to get some peace and quiet.

Your husband "has" drifted off to sleep. :D
