Must/mustn't vs. don't have to

1

In safety rules , always follow the guidelines . ignore warning signs , and you should report any hazard to your supervisor . For casual office days , you wear a suit , but in client meetings you must . If you are unsure , ask a teammate to clarify .

2

Understanding modals helps in giving instructions . The word in most rules . A prohibition is shown with , so you may not do that action . indicates an option is available but not required , such as arriving early if you want to . Context matters and tone affects formality .

3

Daily life examples help solidify the concept . At school , wash your hands before meals . You run in the corridors during passing time . In a library , you whisper , but you don't have to speak loudly either . When assignments are optional , you don't have to submit early , yet you can if you want to improve your grade .
