Your mom sounds hardcore.
My dad is learning to appreciate techno. He was a band director and is a composer of some avante garde and classical so draws similarities between those styles and electronic music's builds, small variations, sound design, emotion, and rhythm. I've had him listen to Bill Youngman, Sasha, Stephan Bodzin. Max Cooper, and Dominik Eulburg and he seems to see the artistic merit. He really likes when electronic artists collaborate with orchestras ala Jeff Mills or The Flashbulb.
He used his record collection to turn me onto a lot of stuff like Sly, Earth/Wind/Fire, Don Ellis, Jethro Tull, Moody Blues, Yes/Rick Wakeman, King Crimson, musique concrete, and especially Frank Zappa when I was younger. Now I turn him onto stuff too.
My mom likes a lot of Gospel, contemporary christian, calypso, bluegrass, zydeco, and klezmer so she's pretty open to anything. She's really liked a lot of the soulful Frankie Knuckles stuff and downtempo I've shared with her but doesn't really like techno, industrial, psytrance, or mimimal. I also used to listen to a lot of punk, hardcore, and ska and she
loves two-tone and third-wave ska.
My wife hates electronic music and says it's too repetitive and doesn't go anywhere but at least she has good taste in reggae and hip hop. She also doesn't dance.
My daughter is 5 and loves beats. She beatboxes along with hip hop, dubstep, and techno. She loves playing with drum machines and triggering samples from the APC while telling me "Dad, I'm mixing. Check me out!" She plays my drums all the time. She dances, loves fire-spinners/poi, and just started hooping. She is awesome.
