Hello.
Is it wrong to say that 'must' and 'have' are not quite interchangeable? Do both of them work in my sentences? If it is a strict obligation I should use 'must' if it's not as strict as with 'must' I can use 'have to'. Am I right?
1. 'You must call the instructor if you want to change the time of your sessions.'
2. 'You have to call the instructor if you want to change the time of your sessions.'
3. 'You must wear appropriate footwear in the gym.'
4. 'You have to wear appropriate footwear in the gym.'
5. 'I would like to apply for this job.' 'Well, you must fill in this form.'
6. 'I would like to apply for this job.' 'Well, you have to fill in this form.'
7. 'I have an injury. 'Well, you really must tell the instrucor about it.'
8. 'I have an injury.' 'Well, you should really tell the instructor about it.'
