Count to ten - or recite " Baabaa black sheep ".

Every now and then someone or something is really going to get your goat. But instead of letting the better get hold of us, raise our voice in anger and our pressure even higher, try counting to ten instead. Those vital seconds will help you gain your composure and remember where you are and who you are. Once you have collected your wits and calmed down, you will have a more appropriate and dignified response.
