My parents were exposed to airsoft gradually as I upgraded from clearsoft to AEG while still living under their roof. They weren't really that surprised at the interest in guns though as I was applying for the military at the time... They more had raised eyebrows at how much I was spending on it but still never said anything about it. Still trying to convince my dad to play though.
My wife thought they were pretty cool and I drafted her to play when my friends and I needed an extra teammate for a local airsoft tournament. Now she has all her own gear and joined a team with me.
