My aplogies for having been rather dictatorial. Reviewing the matter from the question of moral or other responsibility, perhaps I strayed off the mark (it was about 2 a.m.), and on reflection I think that it does not enter into the discussion of these phrases at all. ' Hey, Bill, remember you have to/must take your shoes off when we go inside, otherwise Mum will kill you!' However, if one of the mother's children is talking to one of his friends to alert him to the rules of the household, then he would use 'to have to' or maybe 'must'. In my home the children have to take off their shoes before coming inside.' If she is talking to another mother about how she deals with the problem of muddy feet, then she would probably use 'have to'. With regard to the first one, I still hold that the only modal that could be used is 'should', but in the second case, if we are talking from the mother's point of view, the verb could only be 'must' in her directive. When I suggested that your phrases would have been better with 'should' I was not considering them as direct orders, but rather things that ought to be done in general.

I don't think one person so far has agreed that 'must wear uniforms' is wrong. There are some very sharp people in this forum. In fact, there are debates that have been going on for centuries and that remain unresolved. You will find that most of us agree most of the time about what is correct and incorrect, but not always.ДЄnd frequently when there is a disagreement, there are very well-educated and knowledgeable people on both sides of the debate. There is no central authority that has the right to declare anything as absolutely right or wrong. There is one thing you must/have to remember about English. I would say: 'At my school, students have to wear a uniform.'Д«ut I would consider anyone who marked the other possibility, 'must', as wrong to be following rules that are, at best, highly questionable. 'At my school, students must/have to wear a uniform.' I voted that 'must' and 'have to' are not interchangeable in all situations merely because I know that there are almost always special cases.ДЄpparently your problem is with this sentence: Click to expand.Why are you capitalizing 'Native Speaker'? As a general term, this should be all lower case.
