Hello. Your wording sounds fine to me.

Sounds fine to me, too.

But, if there is a mistake, it is probably in the "must". The fact that "the postman doesn't come on Saturdays" does not mean that it is impossible for him to come. So instead of a "prohibition" (must), we should work with "possibility" (may)...

Does it make sense?

Flavia, yes, it does. I must hand it to you. So I, too, think a may works better there than a must does. Henry? donay? Anyone else?

Dear Márcio and Flávia

I thought I had the monopoly on nitpicking but if I must be part of a cartel, so be it.
