I really want to get into learning the piano, since it seems like such a cool instrument and it sounds great. 
I would also love to learn. I regret never having learned that.  I wonder, do you know much about it?  
I've been researching it recently, so yeah I definitely have some knowledge on it. The first one was invented over 300 years ago which I find unreal.
That is a very long time...I wonder how they came up with it?  I think some other keyboard-type instruments preceded the piano, didn't they?
Well actually, the name "piano" originates from the word "pianoforte", as this was an earlier version of the piano which was very similar to its current version.
That makes perfect sense.  Do you know if older people can learn the piano as well as kids?  I feel like maybe it's too late.
Oh, it absolutely isn't too late for that! It is certainly easier when you are young, but it's better late than never!
How much does a piano cost I wonder
They can get pretty pricey if it's a good quality one or even a vintage one from the earlier days that they were created back in the 1700's.
