Come across

When you come across (something) you run into something, most often good things and without planning to do so. One can come across e.g. stuff (books, speakers, you name it), a person, information, and much more.
Very often used in past tense, because you are telling what you came across.

- I came across a Beatles LP a while ago - the joy!

- Yesterday I came across Dave. Man, he has really aged.

- Have you come across our new boss yet?
