More information...
 Must and have to are very similar,
but there is a small difference. We
normally use have to for a general
obligation (a rule at work or a law).
We normally use must when the
speaker imposes the obligation
(for example, a teacher to students
or a parent to children). But often
you can use either.

You have to speak a little more clearly!

for you and your friends being so drunk and noisy,
throwing bottles, breaking the bubbler, leaving broken
glass and rubbish all over the place and generally messing
up the park)
P.S.: Not a good idea leaving the evidence on your camera’s
memory card...
