Ritually speaking

Theatre is one place where rituals and superstitions reign supreme. Forget tennis players having to bounce the ball three times before a serve. Thespians are a far weirder lot.
I'll start with a few examples. One actor I have worked with gives fellow thespians a match just before curtain up on opening night and says ''touch wood''. A male actor I know gives all the females on the cast a red rose ahead of curtain up, but only if he is the lead in the production. Another male actor has to drink a red drink before each show and becomes quite hysterical if he forgets to bring it.
Then there are the actors who won't talk to people backstage before curtain up because they have to get into character. One would withdraw even before each rehearsal so she could find her ''emotional obligation''. Yet another would crack jokes and bring us all to tears of laughter just before we were due to go on, as a way of distracting himself from thoughts of the job at hand.
I know of seasoned actors who can't eat before a production because of nerves and other still who can't drink for fear of having to use the toilet while waiting backstage.
One actor applies make-up at home, though I think this could have something to do with convenience, rather than superstition.
So, what are my rituals and superstitions? I go over my script once backstage before going on stage to keep the lines fresh. But only once. I don't want to overdo it and create panic in that little brain of mine. Otherwise, it's all fine. No red drink. No red roses. No skipped meals. Just showing up is just about ritual enough for me...
