I was in a city that was in the center of the path of the eclipse last year.  Did you happen to see the eclipse?

Do you mean the solar eclipse of August 2017? I did see it happen, it was incredible! Do you know how an eclipse happens?

Yeah, the moon moves in front of the sun!  It can go the other way, Earth moves between the sun and moon, but it's less impressive.

Do you know how often these solar eclipses happen?
