I ran into an old friend by chance at the library.

My friend is a doctor.

I go to the library every Saturday.

My encounter with him was completely contingent.

I ran into him in the city by chance.

I ran into him by chance in the city.

His ball hit the window and the glass broke.

He is interested in the history of the past.

This old building tells the history of our town.

This old house is the one where my grandparents lived.
