I Accidently said "Macbeth" in a theater and didnt reverse the curse yet! what should i do?!?

I was at a theater today, and this kid said "Macbeth." This other kid said, "Ohhh, you said Macbeth!" And I'm like, "Hey, what did you do? don't you know you can't say "Macbeth" in a theater?" So accidentily, yet stupidly, i said Macbeth. I'm scared, what should i do?
