My cousin is still carrying her Halloween grudge against her sisters. This is like her only Halloween story, and it goes like this:
"I was like maybe 8 years old? It was some age when both candy and presents were really important to me. And I got chicken pox just before Halloween. [nb: This was before there was a vaccine.] I begged my parents, but they wouldn't let me go out trick-or-treating; their concession was that they'd send my sisters out with a spare pillowcase.
"Only on their way home, my sisters stopped a couple houses up the street and dumped all three pillowcases into piles on the sidewalk, and then proceeded to 'exchange' all my chocolate for their Bit 'o Honey's and Mary Jane's.
"They got home and I eagerly went for my candy, only to be confronted by this travesty of all the bad candy. I complained to my parents, who told me to be quiet and just be happy that I got any candy at all.
"A couple months later, both my sisters got chicken pox as well. Except by then it was Christmas, so my grandparents said it was horrible to be sick over Christmas and bought them both extra presents.
"Anyway, that's my childhood grudge that I'm never letting go of: that when I was sick, all my good candy was stolen, and when they were sick, they got extra presents." And then she always ends it: "So - what's your childhood grudge that you're not letting go of?"
