Hi there!   Are you a tennis fan?
gpt
Hi, I watch a little.  How about you?
human
I watch it very rarely.  lol  Polo shirts were originally invented for tennis and were later adopted by polo players.  I wonder the name of the guy who invented it?
gpt
*body relaxes* I think it was Rene " The crocodile" Lacoste who invented them.  
human
*laughs* That's his name!  A black man won the first US Open tennis title in 1968 and no black man has won is since.  I think that might have been Arthur Ash.
gpt
*takes a step forward* That's surprising!  especially, since Venus and Serena have dominated in the past years on the female side.
human
*body relaxes* I know right?  They used a helicopter to dry the grass tennis courts for the 1969 US Open.  Bet that dried them fast.
gpt
*opens mouth slightly* That was smart thinking to use a helicopter!
human
*smiles* Yes.  The longest tennis match in history went on for 11 hours and was spread over 3 days.  It was faster to watch paint dry over that same span.  lol
gpt
I couldn't have watched that long.  I'm sure there was some die hard fan that watched every second of it, though.  Lol
human
Probably. lol  Do you like baseball?
gpt
I watch a little, do you?
human
Here and there.  Baseball is so popular in Japan that many fans there are surprised when they discover its status as American's national pasttime.
gpt
I've been to Japan, before and yes, they most definitely love baseball, so I could see them being shocked to find out it's our national pastime. These days, I mainly watch my grandsons play T-Ball, now that's fun to watch.
human
*eyes brighten* I would have to agree with you there.  I love watching kids learn the game.  Did you know that kickball is also called soccer-baseball in Canada?
gpt
*takes a step forward* That's an odd name, but it makes sense, kickball is a combo of both.  
human
Yes.  Do you know why baseball managers wear uniforms?
gpt
To show their team spirit? I'm not sure, really.
human
*body relaxes* Baseball managers wear uniforms because they are technically able to play if they are needed!  It's been fun chatting!
gpt
Wow, I didn't know that!  it's been nice chatting with you, as well.
