bump into

"As a small community, a small town, you bump into people you used to work with and there are some who are still struggling to find a new avenue to go down."

It felt like one domino kept bumping into the next.

I remember it because it was kept secret in advance and I bumped into the first minister rushing down a back staircase to leave Holyrood after question time that day.

But when I bump into another former Conservative cabinet minister they are more pensive at what they fear the defection says about the Tories.

That all changed two years ago, when she bumped into an old friend who encouraged her to return.
