I was in a band back in the '80s where the two guitarists brought their girlfriends to a practice. We went down to the basement to practice while they stayed upstairs. We took a break a couple of hours later and came upstairs to find the two of them naked and "involved" with each other. They were so into it that they didn't notice we had stopped playing.
Practice never resumed.
Standard rule applies: No photos, no "involved" girls!


Needless to say, he was distracted.
