When you have a funny scene to do but you're shy and you have to hide it.

I'm the Mayor's Wife in Bye Bye Birdie and I have to faint over into the Mayor's arms..3 to 4 times. One time, I even stepped on his foot and I screamed, "I'M SO SORRY!" He just laughed and said, "It's okay!" Ack, I'm such a klutz o(╥﹏╥)o
