I don’t want to step over anyone’s toes

This is a very nice mashup of “don’t step on (someone’s) toes” (don’t offend someone in interfering with their responsibilities) and “go over (someone’s) head” (to speak to one’s superior rather than talking directly). Both involve avoiding confrontation, making it a perfectly formed malaphor. A big thanks to Connie Dykema Fields for unintentionally uttering this one and sending it in!
