Normally, I just think of people in the dojos a dogis to work out with. But one day... I went to a seminar a while back and I noticed an extremely pretty face - right at the moment that I was flying through the air for a big ukemi. My head kind of locked in on her, and time time of froze for my head. The rest of my body kept going at normal speed, so I took a really bizarre fall. My teacher who was teaching as he was throwing me kind of looked at me like "what are you doing?!"
off-topic from OP I know, but...
I've had several, similar experiences at a dojo on a very busy street that had large windows close to the mat. Cars would stop for the traffic light and you'd be mid breakfall, upside down and wind up making eye contact with someone sitting in their car. It's actually a very delightful experience to be able to notice other people, their expressions and to even have a briefly exchanged, "good morning! how are you?" smile mid ukemi.
