Trust me

My youngest has what can only be described as an over active fear of bees. A phobia of biblical proportions. Even today on the cusp of 12, whenever a bee comes within his field of vision, no matter how far away it is, he'll recoil in fear and demand I do something about the clear and present danger. I have no idea where this came from but did once, try to remedy it without success.
The family was frolicking in the pool as families do. Water splashing, laughing and all around a great time in the sun. We had an airbed in the pool too, taking turns trying to stay on whilst the others were all trying to flip you off it. It was one of those magic family times that can only ever get fucked up by the dad.
Griff saw the bee and immediately went into flight mode trying to dodge the insect flying a good 6 or 8 feet above our heads.
"Dad he'll sting me, kill it, make it go away"
"don't be silly son, he has no more interest in you than we have in him"
I continued, "bees don't sting unless they are threatened, its the way they repel enemies so that the others in their group are safe". My calming dad voice echoed across the water as I help Griff up on the airbed out of the water so that I could allay his fears about this innocent little bee going about its business. Griff was not happy about this and wanted to return to the water and safety but I felt it reasonable to let him understand that there was zero risk and that he was being unnecessarily paranoid. He looked at me dis trustingly and I could only reply "trust me".
The bee must have been broken is all I can think. It flew straight down onto his leg and stung him deep.
As Griff's eyes widened and he experienced his first bee sting, his attention turned to me and my inability to keep a straight face. His horror at me was unmistakable. I know its bad to laugh at a youngster as he struggles with nature but hey, you had to have been there! I did try to conceal my smirk but rather unsuccessfully I'm afraid. In one sense, it worked because his pissedness at me over ran the pain of the sting and he maybe felt less as we excavated the pulsing spear from his flesh. I like to think that anyway, trust me!
