"Don't have to" is NOT "must not"


Note:  We rarely use "mustn't" in US English.  Spell out the not.





Please write about two things you must not do and two things you don't have to do.

    I must not drive when I drink
    I must not go out home leaving children alone
    I don't have to do chores on vacation
    I don't have to do pick him up and drop him off my husband when he go to the business trip.
