I love to inline skate in my spare time.  Do you do any inline skating?
No im horrible at it but Id love to know more about it.
Well, you know that inline skates are more like ice skaings.... one single row of wheel rather than four clunky wheels like when I was a kid.
Yea but my balance is terrible so I avoid them, do you know when they were first invented perhaps?
Interesting story.  I thought they were invented in San Diego, but they were used by Russian athletes to train for Olympic long track speed (ice) skating events!
oh wow thats actually really cool, how long have they been around?
Well, a dude named John Joseph Merlin esperimented with them way back in 1760!
wow thats way older than I wouldve imagined, anything else that you know about inline skates?
Actual invention in 1849 in France for an opera singer who was supposed to appear to be ice skating.  Guess that's where Russians got the idea.
