I decided to take this opportunity to meet somebody in my apartment complex.   Bill opened the door and I immediately felt relieved that he was both male and around my age.   Relieved that he was male because I felt a little creepy randomly knocking on women's doors.   Relieved he was my age because I figured he ' d be more inclined to participate.   He had a jovial face which made me comfortable even though he seemed a little unsure about the whole thing at first.   He ended up inviting me in and we had some small talk which relieved some of the uneasiness.  

Bill's response to the question was "invisi-flight," which he explained was the ability to fly while invisible.   He could only be invisible when in flight, but he didn't have to be invisible to fly.   He made sure to include hovering so he could use this invisibility indoors.   It took Bill awhile to come up with this response, but he seemed pretty pleased with himself after his conclusion.

I generally dislike approaching strangers if I have to ask them to do something which they might react put-out to do.   This is just one aspect of my desire to avoid confrontation,   though most of my experiences having such an encounter have been predominantly   enjoyable, certainly nothing I should fret about.   And so I found this encounter with Bill to be virtually painless and for moments enjoyable.   I was surprised that he put so much thought   and energy into coming up with a good super human   quality.   And so I found this encounter with Bill to be virtually painless and for moments enjoyable.
