The reason Toni does not get stung is because she's in no rush and takes her time when she's around the bees
Like Toni I've never been stung when around the bees but my husband has several times even when he's not around them. I'm laid back and easy going, he's hyper and always trying to get things done as quickly as possible. He's learned to slow down when working the bees though. He's dared me to help with a swarm just to see if I am still calm and easy going with thousands of bees surrounding me.
