Looking up at the ceiling of the Sistine Chapel.
Also, when a big spider crawled out of nowhere in the car. I remember it because the scream just erupted out of my mouth right from the pit of my stomach. It was weird. DH was driving and nearly crashed. Kids were traumatised and still talk about it.
The one time I was in a real life or death situation (outside of work) I shouted really concise and precise instructions in very deep
booming that I’ve never used since. DS1 was drowning and I actually took a second to take a deep breath so I could really project my voice. Surprised myself! In a good way (and DS is fine).
