when I was a kid, i found a Katydid and showed my dad. He then revealed that "if I had been a girl" my name would have been Katherine, so he would have the dad joke opportunity of "who ate the last cookie? Katie did!" my dad is big on dad jokes. anyway, that stuck with me hard.
now for my middle name i decided on Elaine as a female version of my old middle name. my parents didn't know until I legally changed my name, and then my mom was pissed, because apparently Elaine is the middle name of her sister, who she doesn't like. oops! still, best possible reason for my mom to get pissed over me changing my name!
