Modals of Obligation (Rules, Advice, and Escaping)
The sun is streaming through the blinds, your head is pounding, and you’re in a bed you don't recognize. Welcome to the morning after. To navigate this highly awkward situation with grace, you need to understand the rules. Do you have to make them coffee? Should you leave your number? You definitely mustn't steal their favorite hoodie. Let's master Modals of Obligation so you don't overstay your welcome.

In English, how strong your obligation is depends entirely on the modal verb you choose. Look at the chart below so you don't confuse good advice with a strict rule!
| Modal Verb | What it means | Cheeky Example |
|---|---|---|
| Must / Have to | 100% Obligation. You have no choice. It's a strict rule. | "You must find your socks before you leave." |
| Mustn't | 100% Forbidden. Do not do this under any circumstances. | "You mustn't wake them up if you are sneaking out." |
| Don't have to | 0% Obligation. It is completely your choice. It's not necessary. | "You don't have to stay for breakfast if you feel awkward." |
| Should / Shouldn't | Good Advice. It's not a rule, but it's a very good idea. | "You should probably wash your face. You have mascara everywhere." |

Remember: 'Mustn't' means DO NOT DO IT. 'Don't have to' means it's your choice.
1. "You look through his phone while he is in the shower! That's toxic!"
2. "You give me your number if you don't want to. It's totally fine."
3. "I have work at 9 AM, so I leave right now."
Use 'should' or 'shouldn't' to give advice for these awkward situations.
1. (He wants to add her on LinkedIn the morning after.)
Advice: You definitely do that. It's so weird!
2. (She wants to steal his favorite jumper because she is cold.)
Advice: You ask him before you borrow it.
