I yam who I yam.. rootbeer anyone?

Can you pinpoint at least 1 specific event from your youth, that has made you the way you are as an adult? I can... my entire adulthood isn't based on this one event, but it's a big part of my personality now. I was a girl scout as a child and liked it for the most part. This is not one of those times. I was in Clarissa Colliers mother's troop and it was rootbeer float night.
Well i don't like rootbeer, and the troop leader said that after everyone had some ice cream in their float that I could have a bowl of just ice cream. okay, no problem.. well I never got that bowl of ice cream. I was very upset, and sat there and watched every other girl there eat a root beer float, including the troop leader and the other moms.. becuase they "ran out". you would think that one of the adults would offer the poor girl some ice cream, but I dont' think they did.. all I know is that I was left out, and it felt miserable.
To this day I can't stand it when a child may feel left out, say at a birthday party, if a friend has Celiac, I'll make a gluten- free cake for them or cup cakes or something because my heart just breaks when something as simple as this happens, because it happened to me. I try to be as accomodating as possible in any given situation, and I don't think anything of it.
Who would've thought that such an event would have such an impact in my life?
